International Vinegar Museum

Roslyn, South Dakota, turned a former community auditorium into the International Vinegar Museum, which opened in 1999 as a distinctive local attraction built around Lawrence Diggs’s vinegar collection and study. In the former 1936 WPA-funded Roslyn Auditorium at 500 Main Street, the museum displays more than 350 kinds of vinegar from around the world and explores how vinegar is made, used, and varied. The building itself had long served as a social and school center after the Roslyn Opera House burned in 1923. Listed on the National Register of Historic Places in 2001, it links New Deal-era public works, local preservation, and Roslyn’s annual Vinegar Festival.
