The South Superior Union Hall was built in 1921 in the southern part of what is now Superior, Wyoming. It is located on Main Street. The hall was built by six locals of the United Mine Workers to accommodate union and community activities in the coal-mining community of Superior, and bears the UMWA logo on its pediment, and the inscription Union Hall over the entrance. Built in 1921, the two-story brick hall's plan is a parallelogram, though to be unique for its time in Wyoming. Read more on Wikipedia
