8. Sign at Entrance to Casa Grande
Casa Grande (large house) served as residence for a succession of mine officials and as a country weekend retreat for wealthy mine investors who often gathered to relax and discuss their extravagant business dealings.
After closing of mine operations at New Almaden, Casa Grande had a succession of private owners and served a number of purposes, including a tourist resort known as Club Alamden.
In 1997, Santa Clara County Parks purchased Casa Grande, dedicating the historic property to the residents of Santa Clara County by adding it to Almaden Quicksilver County Park.

HABS CAL,43-ALMA,4-
Building/structure dates: 1854 initial construction Significance: Casa Grande was built in 1854 as the residence of the general manager of the New Almaden Mining Company, the richest and most productive mining enterprise in North America. Designed by San Francisco architect Gordon Parker Cummings and Henry W. Halleck, then manager of the company, the large two-story brick building was originally covered with stucco, scored to simulate ashlar masonry. Now only the first-floor stucco veneer remains. A low veranda with slender wooden balusters and supporting posts extends across the front and around the side elevations. The grounds were landscaped in 1854, and ca. 1865 a lake between the house and Alamitos Creek was constructed. To formalize the area surrounding the lake, extensive improvements were completed in 1882 under the direction of the company's manager, James Butterworth Randol. Until the early 20th century Casa Grande served as the manager's residence and the entertainment hall of the company. It has subsequently been used as a club, restaurant, bar and prostitution hall, and most recently, for commercial businesses on the lower levels and an apartment on the second floor.
