Fort Caspar, Military post and heritage site in Casper, United States.

Fort Caspar is a military post at a crucial river crossing of the North Platte in Wyoming with reconstructed buildings from the 1800s. The site shows the original layout with barracks, storage buildings, and wooden walls to demonstrate how soldiers worked and lived at this remote location.

Founded in 1859 as a trading post and toll bridge on the Oregon Trail, the site became Platte Bridge Station after the Army took it over to guard emigrants and the telegraph line. It was named Fort Caspar for Lieutenant Caspar Collins, killed in the 1865 Battle of the Platte Bridge Station.

The site tells the story of Plains Indians and settlers who encountered each other at this river crossing. Visitors can see how different groups used this land and what daily life looked like for each.

The site is most accessible during warmer months, with limited operations during colder seasons. Visitors should prepare for outdoor walking across the grounds, as buildings are spread out and weather protection matters.

The fort is named after 2nd Lieutenant Caspar Collins, killed in the 1865 Battle of the Platte Bridge Station; the nearby city of Casper took its name from a misspelling of his first name. The site is now the Fort Caspar Museum and Historic Site, owned by the City of Casper.
