The Beaver Dam Fire Department is responding to a building collapse on Main St.
The store is called Heirloom Antiques, owned by Mary Duvall.
The building is closed on Mondays so no one was inside when it collapsed.
One of the side walls collapsed onto a vacant lot next to the property.
No other buildings were damaged.
The mayor of Beaver Dam estimates the building is about 90-years-old.
Crews are working to stabilize the building and the owner will decide what to do next on Tuesday.
The front wall is leaning towards Main St. so Main St. is currently closed.
