St. Marys Public Library

Featured Sites
In 1904, the Carnegie Foundation awarded the town of St. Marys a grant of $10,000 to build a public library. Local architect J.A. Humphris used classical motifs and St. Marys limestone to design a building that complemented the neighbouring town hall. The children’s wing to the east was completed in 1988.
