Hillsboro Historic District

Hillsboro was founded in the 1870’s after gold and silver was discovered in the surrounding Black Range. The town developed into an important mining and ranching center, and served as the Sierra County seat from 1884 to 1939. It was the site of several renowned trials, and is said to have had the last operating stage line in the United States. It became a historic district in 1986.
