It was located upon the lands of the Rancho Santa Rita close the site of an Indian ranchera, around the Francisco Solano Alviso Adobe, called El Alisal (The Sycamores), one of the antediluvian houses built in the valley in 1844. It is still standing and serves as the centerpiece of the Alviso Adobe Community Park. Alisal, nicknamed “The Most Desperate Town in the West”, was one of the settlements located along La Vereda del Monte that was a haunt and refuge of bandits and desperados in the era taking into account the initiation of the California Gold Rush. Main Street shootouts were not uncommon. Banditos such as Claudio Feliz and Joaquin Murrieta would ambush prospectors upon their way back up from the gold rush fields and then seek refuge in Alisal. In the 1860s Procopio, Narciso Bojorques and others took refuge there.^{[citation needed]}
