The Quarries consist of two former limestone quarries located in southern St. Marys, one of which has been rehabilitated as an outdoor swimming pool. The area became a popular swimming spot with locals after filling with water between 1930 and 1935. In 1945 the town bought the quarries along with 50 acres (200,000 m²) of surrounding land, and now manages it as a public recreational facility. The quarry is Canada's largest outdoor swimming pool.
