Visitors to the Astor House Museum and Clear Creek History Park can explore how the people of Golden, CO, settled a bustling town that served the developing West as a government center and mining supply town. They can tour an 1800s boarding house and homestead where early Colorado pioneers worked and played, see what life was like on the frontier, and hear stories of the people who called this place home. The Astor House was built in 1867 and stayed in continuous operation as a boarding and rooming house until 1971—over 100 years! It rented rooms and served hot meals to lawmakers, laborers, miners, students, and families, some of whom stayed for weeks or even months. Clear Creek History Park recreates the look and feel of a late 1800s mountain ranch complete with gardens, a working blacksmith shop, schoolhouse, and chicken coop (chickens included).

The sites offer tours, demonstrations, educational programs, and occasional recreational and educational events (including living history events).
