About St. Marys

St. Marys sits along the eastern shore of Grand Lake St. Marys, giving this town of about 8,400 people a relaxed, lakefront personality. Having Ohio's largest inland lake right in the backyard means boating, fishing, and shoreline walking trails are part of everyday routine. The community grew around the historic Miami and Erie Canal, and that long heritage still shows in its quiet, tree-lined neighborhoods and preserved brick downtown buildings.

For everyday living, St. Marys City Schools provide solid local programs and plenty of hometown sports pride. Downtown offers locally owned shops, casual dining, and easy access to waterfront parks and green spaces. Commuters also appreciate the quick drives to neighboring hubs like Celina, Wapakoneta, and Lima along State Route 29 and U.S. Route 127. It provides an easygoing, welcoming home base with open water and quiet countryside right outside your door.
