About New Almaden
New Almaden, known in Spanish as Nuevo Almadén, is a historic community and former mercury mine in the Capitancillos Hills of San Jose, California, located at the southwestern point of Almaden Valley in South San Jose. New Almaden is divided into two parts: the mines and much of their immediate surroundings, including historic ghost town settlements in the Capintancillas, which together form the Almaden Quicksilver County Park; and the largely residential historic district surrounding the Casa Grande.
