San Jose home owners learn mining history.Come view a San Jose home turned museum and learn all about mercury mining at the Almaden Quicksilver Mining Museum. Mining began on this site in 1845 when a Mexican cavalry officer discovered that the red rock (cinnabar) that local Ohlone Indians used for painting contained mercury. Mexican mines were seeking mercury to process silver and this substance was very valuable. Over time, Casa Grande was built as a beautiful residence for the mine superintendents and the six acres surrounding the San Jose home were landscaped by the designer of San Francisco’s Golden Gate Park. This San Jose real estate has changed hands many times over the years, but was finally acquired by the County Parks Department so that the public could enjoy it for years to come.
