Fort Sanders, Military fort and historic site near Laramie, United States.

Fort Sanders was a wooden fort built in 1866 on the Laramie Plains, measuring 223 by 400 feet including a parade ground. It was originally laid out for four companies and later expanded for six. Nearly all buildings were wood except the stone guardhouse of 1869, the only structure still standing on the original site.

The installation was established in 1866 as Fort John Buford to protect travelers on the Overland Trail and railroad construction workers in the region. The military post closed in 1882 after the railroad reduced the need for frontier protection.

Two buildings from the fort survive in Laramie. The commander's quarters were moved to LaBonte Park, where they served as a community center and since 2010 have housed the nonprofit Feeding Laramie Valley. Another building became the Cavalrymen Supper Club.

Parts of the fort remain at the original site outside Laramie while others are located within the city, requiring visits to multiple locations. Plan to see different sections by exploring both the countryside site and downtown Laramie.

The stone guardhouse built in 1869 is the only structure still standing on the original site. At least two other fort buildings were moved to Laramie and survive there: the commander's quarters now serve as the headquarters of the nonprofit Feeding Laramie Valley in LaBonte Park, and another became the Cavalrymen Supper Club.
