New Almaden (CA) (Images of America)

In a rocky, wooded canyon south of San Jose lies New Almaden, a settlement that grew near the oldest and richest mine in California. Discovered in 1845, its quicksilver payload was once crucial for gold and silver processing and manufacturing munitions. It produced over $75 million from the deepest network of quicksilver shafts on earth. Diverse laborers populated this thriving town, creating neighborhoods called Hacienda, Englishtown, and Spanishtown, along with the mine manager's stately home, Casa Grande. Although the mines are now closed and the great ore furnace cold, the Casa Grande still stands along with a residential community that was placed on the National Register of Historic Places in 1963.
