The Sweetwater Brewery, also known as the Green River Brewery, was built in 1900 in Green River, Wyoming. The present structure is the surviving remnant of a three-building complex comprising an office/saloon, engine house, and the present brewery building. It was the first brewery in Wyoming, with operations dating to 1872 when Adam Braun began the business, the first of a series of ethnic German brewers. The brewery was further developed by Otto Rauch and Karl Spinner. The present structure was built by the fourth proprietor, Hugo Gaensslen, a Chicagoan who decorated the building with turrets reminiscent of the Chicago Water Tower. The two story building is composed of rock-faced ashlar sandstone, mostly quarried 1.5 miles away. The fanciful turrets feature mock-medieval features such as merlons and crenels. The largest tower is on the southwest corner and features a flagpole topped by a large ball. Gaensslen concentrated on brewing, leasing the adjacent saloon to an operator.
