At the Canadian border, Eastport is, as its name suggests, the easternmost city in the United States. It is here that, in 1604, the first French people to arrive in the New World settled. Discover their story at the Saint Croix Island International Historic Site. In the late 19th century, this charming town in Maine grew significantly as a result of the development of the canned sardine industry. At the time, the town boasted more than a dozen sardine canneries. The architecture and some mansions from this period live on, affording the town a distinct elegance. One of the attractions of this town is undeniably its proximity to the Old Sow Whirlpool, the largest tidal whirlpool in the Northern Hemisphere, where visitors can watch the birds and marine mammals that come to feed on the nutrients driven up to the surface.
