Located in an 1860s limestone house with an impressive 2019 addition, this museum is on 13 picturesque hectares (32 acres) overlooking the local quarry swimming hole. The site includes a major league-style baseball diamond, two children’s fields and picturesque walking trails. The museum showcases artifacts and memorabilia, and pays tribute to baseball’s impressive Canadian roots and the accomplishments of inductees.

A small stone church was built on this site in 1859 and a rectory to the east was constructed about the same time. The rectory still survives. The old stone church served the congregation until this magnificent building was opened in 1893. The tower in the centre rises 21 metres (69 feet), topped by a soaring 18-metre (61-foot) spire.

In 1857, a plain church of local limestone was erected here. It still forms the heart of St. James, making this the town’s oldest place of worship in continuous use. In the mid-1880s, the church was renovated. The roof was raised and entrance porches were added. Additionally, the southwest corner was given a Gothic tower and the sanctuary was extended.

When George Tracy — one of St. Marys' earliest settlers — built this house for his family in 1854, it was the largest residence in the area. The neighbourhood park surrounding the building today is what remains of the extensive grounds of this “Castle in the Bush.” A fine example of domestic limestone construction, it has been a museum since 1959.

In 1904, the Carnegie Foundation awarded the town a grant of $10,000 to build a public library. Local architect J.A. Humphris used St. Marys limestone, which complemented the neighbouring town hall. The new library provided accommodation for a municipally owned collection of books that had been previously housed in the town hall. The children’s wing was completed in 1988.
