The Fort Laramie Cavalry Barracks was constructed in 1874 and continuously
occupied until the National Park Service began interpretation of its
history. A restoration effort required mitigative excavations in the
building's interior and along the west side. Over 5,000 artifacts were
recovered that physically document the changing uses of the building
through time.
Several features were identified that relate to the use of the site since
at least the early 1860s. The foundations of a structure predating the
barracks were discovered beneath the floor. The probable area where the
lime concrete was mixed for the wall construction was identified. The
barracks washroom dry sump was excavated, and a late military period or
early civilian period trash pit was sampled.
