The Saint Vincent Archabbey Gristmill, built by Benedictine monks, has been in continuous use since 1854. It has endured flooding, mine subsidence, and the changing economic landscape to serve as a symbol of Western Pennsylvania's agricultural heritage, and of the vision of Saint Vincent founder Boniface Wimmer. Boniface Wimmer envisioned the monastic foundation as a self-sufficient community. The monks worked the soil to provide all kinds of grains, fruits and vegetables for themselves and the students. Now, the Gristmill houses a General Store, Coffeehouse, and Museum. It is still operated by the Benedictines of Saint Vincent Archabbey.
