Frankfort Mineral Springs
Frankfort Mineral Springs was a famous resort and health spa initiated in the late 1790's. The "Frankfort House" serviced patrons in the summer months for over a century and closed in 1912.
The waters contained fifteen different minerals thought to have medicinal qualities. A historic marker was erected on the site by the Beaver County Historical Research & Landmarks Foundation.
The mineral springs are now part of Raccoon Creek State Park in Hookstown, PA (near Pittsburgh).
