Discover more about Casa Grande

Casa Grande, a commanding presence in the New Almaden Historic District of San Jose, offers a captivating journey back to the mid-19th century, when quicksilver mining dominated the region. Constructed in 1854 under the direction of Captain Henry Halleck, then the manager of the New Almaden Quicksilver Mine, the Casa Grande, meaning "Big House" in Spanish, was designed as a hotel, but quickly became the residence for the mine's general manager and a symbol of the mine's prosperity. Designed by architect Gordon Parker Cummings, the two-story structure was built with a blend of adobe, brick, and wood, originally covered in stucco to resemble ashlar masonry. The mansion boasted 27 rooms, reflecting the affluence of its occupants. The Casa Grande not only served as a residence but also as a venue for social and political events, hosting wealthy mine investors and VIPs like William Sharon, D.O. Mills, William Ralston and James Fair. The grounds surrounding the Casa Grande were meticulously landscaped, with John McLaren, the designer of San Francisco's Golden Gate Park, assisting with the formal landscaping of the grounds. A lake was added between the house and Alamitos Creek, further enhancing the estate's beauty. The New Almaden mine was the first operating mine in California and the most productive mercury mine in North America. Mercury, also known as quicksilver, was crucial for extracting gold and silver during the Gold Rush era, making New Almaden a vital contributor to the state's economy. The mine attracted a diverse workforce, including Cornish, Mexican, and Chinese laborers, each bringing their unique skills and cultural traditions to the community. The town of New Almaden was divided into three enclaves: the Hacienda, Spanishtown and Englishtown, each reflecting the cultural backgrounds of its residents. As the mines began to deplete around the turn of the century, the Casa Grande transitioned through various roles. It was sold in 1927 and transformed into a resort and recreational facility known as Club Almaden. A dance floor was added, later becoming a ballroom and then a live theater called the Opry House. In 1997, Santa Clara County acquired the property, and in 1998, it became the home of the Almaden Quicksilver Mining Museum. The museum's collection originated from Constance Perham, who displayed mining artifacts in her house in New Almaden. Today, the Casa Grande houses the Almaden Quicksilver Mining Museum, offering visitors a fascinating glimpse into the history of mercury mining and the lives of the people who lived and worked in New Almaden. Exhibits showcase the technology used to extract mercury from cinnabar ore, the cultural diversity of the mining community, and the opulent lifestyle of the mine manager's family. Three rooms are furnished with antiques, recreating the elegant atmosphere of the mine manager's residence. Visitors can explore the museum's exhibits, wander through the surrounding gardens, and learn about the history of the New Almaden mines. The museum also hosts events throughout the year, such as "Play Like a Miner," where visitors can experience aspects of mining life. The New Almaden Historic District, where Casa Grande is located, offers a 1.6-mile walking tour showcasing historic homes and buildings, including the Hacienda Cemetery, La Foret Restaurant, and St. Anthony Catholic Church. Visiting Casa Grande and the Almaden Quicksilver Mining Museum is an immersive experience that brings to life the story of a significant chapter in California's history. It is a place where visitors can connect with the past, learn about the challenges and triumphs of the mining community, and appreciate the legacy of the New Almaden Quicksilver Mines. Casa Grande stands as a testament to the ingenuity, hard work, and cultural diversity that shaped the region. Its transformation from a mine manager's residence to a museum reflects the evolving landscape of the Almaden Valley and the enduring importance of preserving its history for future generations. A visit to Casa Grande is a journey through time, offering a unique perspective on California's industrial heritage and the human stories behind the quicksilver boom.
