A Maryville building collapsed Thursday morning.

Emergency personnel responded to a wall collapse at a Maryville bar around 8 a.m. on north Main Street.

No one was inside the building when the south wall collapsed into an alley.  The building houses a Maryville bar called The Pub.

The bar was closed after it exchanged owners and was undergoing remodeling.  It was set to open by the beginning of next year.
