New Almaden, Mercury mining heritage site in San Jose, California, US
The New Almaden district encompasses 4,147 acres of land, featuring preserved mining structures, residential buildings, and the Casa Grande mansion along Alamitos Creek.
Established in 1845, New Almaden operated as the first and largest mercury mine in California, producing essential materials for gold processing during the Gold Rush era.
The mining community included Mexican, Cornish, and Chinese workers who established distinct neighborhoods, leaving their mark on local traditions and architecture.
The New Almaden Quicksilver Mining Museum, located in Casa Grande, displays mining artifacts and offers guided tours through the former mining settlement.
The Carson-Perham Adobe, constructed between 1848 and 1850, stands as one of the oldest existing structures built by Mexican miners in the region.
