Historic Littleton, Inc. and the City of Littleton will celebrate the 150th birthday of the Denver and Rio Grande (D & RG ) Railroad depot located at 5790 S. Prince St. on Saturday, May 16, at 2:00 p.m.
The D & RG Railroad was the first railroad to provide rail service to Littleton, arriving in 1871. Four years later, in 1875, the depot was built with rhyolite stone quarried from Castle Rock. The depot was designated as a Littleton landmark over 50 years ago.

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.
