The building was originally built in 1937 by Dr. Branton of Branton Properties. In 1938, Thrifty Drug Store was the first business in the north side of the building and New Super Food Mart was on the south side. In 1942, Paffrath’s Jewelry came into the south side of the building until it later moved to the Kandi Mall sometime in the 1980’s. Don Miller says that a store called Gambles also occupied the south side of the building before 1949 when Thrifty Drug, owned by Arnold Rosenfield, expanded into the entire building. Thrifty eventually relocated to the Kandi Mall as well. In 1995, the north and south sides of the building was the Salvation Army Thrift Store and receiving center. In 2002, the Barn Theatre next door purchased the old Drug Store building to provide additional space for storage and to extend their programming. On May 30th, 2014 Willmar Downtown Development and the Preservation Alliance of Minnesota purchased the building from the Barn Theatre. The two partners named the building Historic 313 on Fourth Street and are working to bring about a brighter future for the building and for downtown Willmar. It is currently being redeveloped for a local food initiative, as well as some local businesses, including a brewery!
