Kennebunk, ME

First settled in 1621, the town developed as a trading and, later, shipbuilding and shipping center with light manufacturing. It was part of the town of Wells until 1820, when it incorporated as a separate town. "Kennebunk, the only village in the world so named," was featured on a large locally famous sign attached to the Kesslen Shoe Mill on Route One.
