The College Inn Bar is the oldest established business in Douglas, Wyoming and Converse County to survive in its original location.

The 1906 structure is a two-story masonry building, occupying the site of the frame Pringle's bar, which was moved two blocks away and which still survives.

The barroom features taxidermy mounts and an arched vision screen with stained glass inserts, crowned by two stuffed golden eagles.

Beyond the barroom is a lounge that used to feature ten curtained private booths, removed during Prohibition.

The lounge retains call buttons and painted murals.
