Columbia Historic District
Why it's listed
Columbia is a former gold rush town four miles northwest of Sonora in California's Mother Lode country. Rich placer gold was found there in March 1850, and a vast network of ditches, flumes and a 60-mile aqueduct later brought the water needed to work the deposits. By the mid-1850s the town had thousands of residents, hotels, saloons, stores, churches and fraternal halls. Fires in 1854 and 1857 destroyed the early frame buildings, and the town was rebuilt chiefly in brick with iron doors and shutters to resist fire. Mining declined after 1860, yet Columbia was never fully abandoned, and its population stayed near 500. Because of that continuity, many original buildings survive and few modern structures intrude. The historic core was set aside as a state park in 1945, and 39 historic structures are included, among them hotels, banks, stores, firehouses, churches and a school. Restored interiors show the gold rush period, and the district was recognized as an outstanding example of a mining town.
Significance in brief: Columbia, the "Gem of the Southern Mines," is described as probably the best preserved of the early gold rush mining towns in the Mother Lode. After fires in 1854 and 1857 the town was rebuilt chiefly in brick, and it never became a true ghost town. Its many surviving original buildings reflect an 1854-58 mining town and give a vivid impression of the gold rush.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
