 Visit the Monday Club - A Julia Morgan Masterpiece


Location: The Monday Club, San Luis Obispo, California  93401

A visit to The Monday Club is a unique opportunity to tour a 1934 vintage women’s club designed by Architect Julia Morgan. During the first quarter of the 20th century Julia Morgan was the first woman granted an architectural license in California, the 19th Amendment granting women a constitutional right to vote was ratified by Congress, and The Monday Club was founded by a dynamic group of women in 1924. Similarly significant contributions by civic-minded women were being made elsewhere in California and in the world.

Visitors to The Monday Club will enjoy viewing original architectural features including murals, hardwood herringbone floors and the open truss system that was a recurring element in many of Miss Morgan’s buildings.

Integral to appreciating the history of The Monday Club is an understanding of what was occurring elsewhere in our country and the world during this period. On display will be an educational timeline that we have created depicting 100 years of history and events in San Luis Obispo, California and the world. Interpretive discussion of the timeline will be part of the docent-led tours that will be ongoing throughout the Doors Open event and a scheduled lecture on Saturday, June 11, 2022, with Laura Sorvetti a Julia Morgan scholar will be included.

The mission of The Monday Clubhouse Conservancy is to preserve and restore the historic landmark known as The Monday Club of San Luis Obispo and to provide public access to the landmark for educational purposes, and to carry on other charitable and educational activities associated with this goal as allowed by law.

The Monday Club was nominated to the National Register of Historic Places in 2016, listing 16000245.

The Monday Clubhouse Conservancy is a 501(c)3 nonprofit organization.

Architectural Tour of Bernard Maybeck's Masterpiece - First Church of Christ Scientist, Berkeley

Location: 2619 Dwight Way, 94720 Berkeley, Berkeley, CA 

Bernard Maybeck's 1910 masterpiece, First Church of Christ, Scientist, Berkeley, is a world-class architectural treasure and National Historic Landmark. It is a brilliantly creative integration of Arts & Crafts, Byzantine, Romanesque, Japanese, and Gothic Revival, built of modern industrial materials yet designed to be unusually home-like and connected to its garden and community surroundings. Across from today’s People's Park, the center of Berkeley's counter-culture movement, the church's warm and honest character is defined by simplicity, unity, harmony, beauty, light and peace. In terms of light and space, Maybeck’s Masterpiece is the first truly American church.

 Behind the Doors of the Berkeley City Club


Location: , Berkeley, CA 

The club docents will introduce you to Miss Morgan, who was the first woman architect certified by the Ecole des Beaux-Arts in Paris, and will lead you through the vaulted halls and arcaded courtyards of this medieval fantasy.

The Berkeley City Club is known for its steel-reinforced concrete walls and ceilings (artfully fashioned to look like wood), leaded glass windows, interior courtyards and magnificent indoor swimming pool. The building is a blend of Romanesque and Moorish styles of architecture common to the areas surrounding the Mediterranean Sea.

Julia Morgan’s engineering skills, evident in the seismically solid building exterior, were matched by her attention to the interior designs for furniture, light fixtures, distinctive fireplaces and even dishes.

Constructed in 11 months, this six-story landmarked building opened in 1930 as the “Berkeley Women’s City Club” with a membership of over 4,000.

The Club’s founding group of women, all involved in separate civic, social, athletic and philanthropic causes, wanted to come together in a single, impressive, multi-use building. At the height of her career, Bay Area architect Julia Morgan was the natural choice for their project.

Originally a social club and residence for women, the Berkeley City Club has welcomed both women and men since 1962. Today it serves as a club, hotel, restaurant, events space and conference center.

 Baby Observations and a Chinese bunkhouse: What they tell us about life on the Shinn Ranch


Location: 1251 Peralta Blvd., Fremont, California  94536

Dr. Milicent Shinn’s child development studies were carried out at the Shinn ranch. Her observations of her niece were the basis of her PhD dissertation (1898) and later book, The Biography of a Baby (1900). Her study notebooks recording her observations of her nephew Joseph Jr. were recently discovered in the attic. In addition to observations about Joe Jr.’s language development and motor milestones, Dr. Shinn also recorded glimpses of family life, like Joe Jr’s love of Grandma Lucy and their Chinese cook, Fong Gan (perhaps because they both supplied him with sweet treats).

Efforts are underway to raise money to restore the fragile 100-year-old bunkhouse from the Shinn ranch “China Camp.”  The building will be used to highlight the historic role of the Chinese immigrants at the Shinn ranch and in our community. This history is recorded in the letters, ledgers, and photos of the Shinn House Museum. The building will be included in the nomination of the Shinn Ranch to the National Register.

The Shinn House Museum, at the back of the Shinn House, is open 1-4 pm. The Chinese Bunkhouse Preservation group will be on hand with the “Chinese Roots: Sketches of Life in the Washington Township” exhibit and will guide people to the bunkhouse.

Tours of the two story Victorian Shinn House are 1-4 pm first come first serve, for a donation $4 adult $2 child.

Location: Shinn Historical Park & Arboretum, 1251 Peralta Avenue, Fremont CA. Parking is free.

 Rebirth and Restoration of the Rancho Higuera Historical Park


Location: 47300 Rancho Higuera Rd., Fremont, California  94539

Guests are invited to visit the Galindo-Higuera adobe, located on the Rancho del Agua Caliente. This rancho was awarded to Fulgencio Higuera in 1839 by then Governor Juan B. Alvarado. At the time, this land consisted of 9,563 acres or 15 square miles, and it supported 11,000 head of cattle and several hundred horses.

Our guests can still enjoy the verdant green hills and can imagine what it looked like with no fences, and with rancho cattle dotting the hillsides.

140 years later, in 1979, the adobe was falling down. Historians, architects, preservationists, and archaeologists agreed that the adobe was significant and worth saving; and thus, the restoration began. A total of 7,500 bricks had to be made to replace those that were missing.

Inside the building now are displays that describe the hide and tallow trade, a video that shows how the land was used from the Ohlone period to the restoration, as well as a display of Ohlone artifacts.

This adobe and its current 20 acres represent an important chapter in Spanish-Mexican history in California, and we at the Washington Township Museum of Local History are happy to share this gem with you.

Special activities for children (and adults): brick making, branding with paint, design-a-brand, corn husk and/or clothespin dollmaking, candle dipping, play horseshoes, and rope the steer.

Rediscovering Vintage Lost & Found Films and Why They Matter - Special Presentation and Tour


Location: Niles Essanay Silent Film Museum & Edison Theater, Fremont, California  94536

There are elements of a scavenger hunt, a time-sensitive escape room and the Amazing Race when it comes to locating and preserving vintage films. What do you do when a film is falling apart and decomposing before your eyes? Is there any point in saving it? Many times in early filmmaking there were no titles or credits listed. How can one know what the film is about, when it happened and even who made it if there is no more information accompanying the spool of nitrate? And why does it matter? Find out how the state of construction of buildings as seen on the celluloid, listings in city directories can help document a time and place. Also, why other more minute details like rain puddles in the streets, license plates on cars, angles of the sun, non-standard film perforations, and (thankfully) excruciating detailed people who get every bit of information listed on a website or database help researchers find out the facts about a film made more than a century before. What research methods were employed before the internet made more things possible and why they sometimes still must be used to get answers. Film Historian and filmmaker David Kiehn will share some of the stories of how his work has gotten films the credit they deserve, whether it is the still well-known A Trip Down Market Street, post-earthquake footage from 1906 San Francisco or a Ringling Brother Circus Parade from 1902.

 Visit the Washington Township Museum of Local History


Location: 190 Anza Street, Fremont, California  94539

Visit the museum to learn about the history of the Tri-City, from the Mission and Rancho Eras through to pre-incorporation — back when Fremont, Newark and Union City were made up of farms, ranches and dairies, and later, after the cities incorporated, suburban communities. Visitors will discover how the waves of families who moved here lived, worked, and established a thriving small-town community.

On view through September 2023: “Depicting Historical Places: Tri-City Artists & Their Work” – This exhibit features creations by local women of the past, including mosaics by Alice Ebright, photographs of historic buildings taken by Julianne Howe, and writings by Milicent Shinn. Artist Nancy Pratt’s watercolors of the five villages of Fremont round out the exhibit. These pieces interpret many of the same sites throughout the Tri-Cities across multiple decades, which showcase the multitude of possible interpretations of our local area.

Bonus: Our museum is a former fire station! Opened in 1954, the Mission San Jose station operated as a volunteer firehouse, as all former fire departments had been. Two years later, in 1956, Mission San Jose became part of the newly formed City of Fremont, and the volunteer fire department continued their service until the station officially became Fire Station #4 for the City of Fremont. In 1989, a new fire station was built on the corner of Paseo Padre Pkwy. and Pine St., where it is still housed today. In 1992, The City of Fremont leased our old fire station building to two local non-profits, and the Washington Township Museum of Local History opened its doors here later that same year.

We also feature an all-native California garden.

 Mannequin Madness: where mannequins go to be Repurposed & Reused with Interactive Art Activities


Location: 1031 Cotton St, Oakland, California  94606

When the California Cotton Mills (Oakland Landmark #24) was built in 1883, it was the largest cotton mill west of the Mississippi River. At its peak the Mill covered 12 acres and employed 1,500 workers, mainly Portuguese immigrants . The mill was demolished in 1956 for the construction of the Nimitz Freeway which literally cut though the center of the mill.

Mannequin Madness is located one of the few remaining structures from the Cotton Mill. We are the largest mannequin recycling company in the USA. We keep mannequins from going into landfills by acquiring them from retailers who are closing or remodeling locations. We then resell mannequins to businesses and private individuals who reuse or repurpose them.

A visit here offers the following:

videos and signage about the history of the building and surrounding area.

Come visit Treasure Island’s fabulous Art Moderne air terminal, listed on the National Register.

Our building was constructed in 1937/38 to accommodate Pan American Airways and its passengers during the years of the Clipper flights across the Pacific (1938-1945), and serving as the Administration Building for the Golden Gate International Exposition, 1939-1940. Treasure Island then (1942-1997) became a major naval station especially during World War II and subsequent Navy and Marine engagements in the Pacific. Now the building is headquarters to the Treasure Island Development Group, in charge of the new redevelopment on the island as its ownership is transferred from the Navy to the City of San Francisco. Visit us to see the wonders of the 1939/40 GGIE and learn about the naval years as well as the ongoing redevelopment. We will have tours, speakers, exhibits, objects, and perhaps music!

 Special Doors Open Tours at the Kentucky Mine and Museum | NEW THIS YEAR!

Location: 100 Kentucky Mine Road, 100 Kentucky Mine Road, Sierra City, CA 96125, Sierra City, California, United States

Located on highway 49 in the historic gold mining town of Sierra City, the Kentucky Mine Museum is a real treasure. Tours take visitors from the entrance of the gold mine with its blacksmith shop, into a miners’ cabin, and on through the well-preserved stamp mill. By the end of the tour, guests will understand from beginning to end the workings of a California stamp mill.

The Kentucky Consolidated Gold Mining Company was formed in 1853 and was expanded to ten stamps in 1888. The mine was abandoned during the turn-of-the century and reopened by Emil Loeffler and his son Adolph. The Loefflers rebuilt the mill on the current site during the 1920s, reusing salvaged equipment from local mines from this early period. The mill was equipped with two water-powered Pelton wheels that turned belts and two 5-battery stamps in crushing ore to particles fine enough to pass through fine screens and onto the amalgamation shaker tables. Adolph Loeffler died tragically in a mine explosion in 1944; however, the family worked the ore up until 1953. In 1974, the mill was transferred to the Sierra County Historical Society to serve as stewards.

Today the park displays old mining equipment on the grounds and its museum exhibits let visitors glimpse into Sierra County’s rich history. Come visit the Kentucky Mine Museum to step into the past!

This tour, guided by the building’s Creative Director, will highlight the site’s 156-year history and how it impacted the region.

By joining this tour, you support our mission and gain insight into downtown San Bernardino’s attributes: its rich history, culture, and current revitalization efforts- more than what its stigma describes.

One day only. Groups are encouraged.

Tour times: 10:15 am. 2:15 pm. 5:15 pm.

Arrival window of 15 minutes before your tour begins.

We will feature a walking tour portion of the building’s architecture, artwork, and offices. We will also show historical photographs, videos, and artifacts.

An interactive commemorative gift is included.

 Exclusive Look at the Stunning Lobby of the 1925 Nirvana Building


Location: 1775 N Orange, Los Angeles, California  90028

In 1925, architect E. M. Erdaly designed an Oriental Revival building that featured a pagoda roof, a pagoda shaped sign out front, and other interesting oriental details . Owners promoted its unique look as early as 1926, calling it the “most exclusive apartments in Hollywood” in a Los Angeles Times ad.

On July 13, 2005, the building was named cultural historic monument #816 for Los Angeles.

Once richly decorated with wall paintings and plaster reliefs, the lobby of the Nirvana building was stripped of all the decorative details and painted white and red around the 60’s . The restoration process , carried out by EC2 Art Conservation included the uncovering of the richly decorated walls and the restoration of all the murals. Elisabetta Perfetti, the lead Art Conservator on the project will be there explaining to visitors both the history of the building and the restoration process.

 Tour of Ventura's Newest Hotel, the Historic Elks Lodge.


Location: 11 S Ash Street, Ventura, Ventura  California

The former Ventura Elks Lodge BPOE 1430 is now Ventura’s coolest boutique hotel. The grand downtown building, constructed in 1928 in the Spanish Colonial Revival style, was occupied by the Elks fraternal organization from 1928 to 2004. When the Elks tried to sell the property, it sat on the market because the building was desperately in need of maintenance and was difficult to rehab for a change of use. Now the building has been transformed into the Hotel San Buena, a 32 room boutique hotel rehab that spared no expense on the details and was able to marry rehabilitation of historic elements with a compatible hotel use. The upstairs Elks Temple ballroom on the third floor is now the Velvet Hall event space. The expansive Lodge staircase, that was the only access to the upstairs Elks Temple, has been restored and an elevator added in the new addition for ADA access. Old fixtures and furnishings have buffed, burnished, reupholstered and rewired to include in the guest rooms and lobby. Sixteen new hotel suites have been sensitively added to the former parking lot at the back of the Lodge and follow the Secretary of the Interior’s Standards with a three-inch gap between the buildings.

 Lemon Grove Parsonage Museum (1897) and the H.Lee House (1928)


Location: Treganza Heritage Park (both buildings in the park), Lemon Grove, California  91945

The Parsonage Museum (1897) was the original church in Lemon Grove. It fell into disrepair and the Lemon Grove Historical Society raised the funds to have it moved to its present location. Volunteers restored the Parsonage and volunteers still man the Parsonage. We have permanent displays of the history of Lemon Grove and change out a gallery throughout the year. Presently, we have the story of the Treganza Family and in 2020 we had the park renamed for them. Alberto Treganza designed and build the famous Lemon Grove Lemon for a parade and it has become a permanent fixture in our city. He was also the designer of the Spanish style Police Station in downtown San Diego across from Seaport Village as well as many private homes in San Diego.

The H. Lee House was saved from destruction when Highway 125 was built. With the help of Caltrans and fundraising by the Lemon Grove Historical Society, “Lady Lee” was trucked down to its home in the park in 2002. Citizens lined the street as she made her way, electric wires and trolley tracks were no obstacle for her! The Lee House is the home of Lemon Grove’s archives and where we present our History Alive lectures once a month. The Lee House can also be rented for events of all kinds.

The Parsonage can be a docent or self-guided tour and we will select archives to share as well as a tour of the house and lovely gazebo and gardens at the H. Lee House. We also have a Community Garden next to the Parsonage which we will arrange to be open for tours.
