Abandoned places in Sacramento
5 abandoned and forgotten places around Sacramento, Preston Castle, Keystone Mine and Alabama Mine among them — and for each one, whether you can legally visit.

They spread across Ione, Amador County, Amador City, Penryn, Crockett and 1 more area, so two or three can make a whole afternoon. 4 of them cost nothing. Every entry is hand-vetted against real sources — not scraped off a top-ten list or averaged out of crowd ratings.

Preston CastleOpen to visit
Built in 1894 to look like a school rather than a prison, this Romanesque pile once held 800 boys at a time as California's reform school for juvenile offenders — Merle Haggard and Eldridge Cleaver both did time here — before it closed and sat half-collapsed for decades. Ghost Adventures and Ghost Hunters have both filmed inside, and the nonprofit that now owns the building runs actual overnight paranormal investigations through its empty dormitory wings.
-
Keystone MineView only
Established in 1853 through the consolidation of several smaller claims, the Keystone Mine became one of the most lucrative gold mines in California's Mother Lode, producing approximately $24 million in gold before closing in 1942. Today, the site is abandoned, leaving behind massive concrete mill foundations right off Old Highway 49 and a rusted steel headframe rising above the trees on the hillside. While the historic Mine House across the street has been converted into a hotel, the actual mine workings are sealed and caved.
-
Alabama MineDo not enter
Originally worked in the 1850s, the Alabama Mine (also known as the Alabama-California Mine) was a gold and silver lode mine that featured a 20-stamp mill and a shaft reaching depths of up to 1,000 feet. The mine was revived in the 1930s but permanently closed during World War II due to wartime gold mining restrictions. Today, the historic site is completely inactive, with its remnants situated on private residential land.
-
Garden City WreckageView only
Built in 1879, the S.S. Garden City was a 208-foot wooden paddlewheel steamboat that ferried passengers and automobiles across the San Francisco Bay. After retiring in the 1930s, it served as a floating fishing resort at Eckley Pier until its abandonment in the 1970s. A 1983 fire burned the vessel to the waterline, leaving only its massive iron boilers and paddlewheel hub rusting in the mudflats today.
-
Coloma Jail RuinsOpen to visit
Located within Marshall Gold Discovery State Historic Park, these stone ruins are all that remain of El Dorado County's third jail, completed in 1856. Built of thick granite blocks and steel to hold Gold Rush-era criminals, the prison was decommissioned in 1862 and partially dismantled for building materials. Today, the weathered stone walls and a nearby rusted iron cell stand in an open field as a testament to frontier justice.
