I love the post office in Saults Ste. Marie, Ontario, for its stone foundation, its humble brick second and third stories, and its insouciant cupola. The city’s name comes from “Saults de Sainte-Marie,” archaic French for “Saint Mary’s Falls”, the rapids of St. Mary’s River that connect Lake Superior and Lake Huron. And I am especially pleased that the building survives to this day, and serves as the Saults Ste. Marie Museum.
