Grass Valley, California, was founded during the Gold Rush in the mid-1800s, becoming a key mining town due to its rich gold deposits, especially the Empire Mine.
By the 1850s, it was a thriving community and economic hub. After gold production declined in the 20th century, the town shifted to agriculture, timber, and later high-tech industries.
Today, Grass Valley is known for its historic charm, arts scene, and outdoor activities, while retaining its Gold Rush heritage.
