Grass Valley’s story is rooted in the California Gold Rush, when
  miners, merchants, and families from around the world built a
  thriving community in the Sierra Nevada foothills. The city
  quickly grew into a cultural and economic hub, blending rugged
  frontier spirit with Victorian-era charm. Today, Grass Valley’s
  historic homes, brick storefronts, and preserved landmarks offer
  a glimpse into that vibrant past. The Heritage Homes Walking Tour
  celebrates this legacy, guiding visitors through neighborhoods
  where generations lived, worked, and shaped the character of
  Nevada County. From Gold Rush pioneers to 20th-century
  innovators, the city’s history lives on in the architecture and
  stories that still line its streets.
