An overnight fire in Ridgway heavily damaged the Ferragine Spa and Pools building.
Crews from Ridgway, St. Marys, Johnsonburg and Wilcox responded to the Main Street property around 11:30 p.m.
The roadway was closed for a while as crews battled the blaze.
West Penn Gas Company was also called out due to the chemicals.
The borough manager says the building has been owned by Jim Ferragine for over 40 years and a tanning salon was just opened in the upstairs on Monday.
A state police fire marshal was called to investigate.
