Littleton Museum

Littleton Museum brings nearly 150 years of local history to life through immersive, hands-on exhibits that explore how the Littleton community was built and how it has grown. Step inside a working blacksmith shop modeled after a 1903 structure in Ohio, wander an 1860s living history farm that recreates a pioneer homestead from Littleton’s settlement era, and discover historic artifacts honoring both the 150th anniversary of Colorado’s statehood and the 250th anniversary of the nation’s founding. Together, these exhibits connect everyday lives, craftsmanship, and major milestones into one vivid story of Littleton’s past.
