Portland
With its large population, financial and legal services, cultural and historical attractions, and “Old Port” dining and shopping district, the City is the only true metropolitan area in the state. See photos. Portland harbor is a working waterfront serving tankers, tourists, and fisheries, along with recreational boating from year-round and summer residents. Ferries connect the mainland to the many Casco Bay islands. Settled in 1632 and incorporated as a town on July 4, 1786, Portland became a city in 1833.
