Built in 1807, it is the only known surviving tower of its type in the United States. Using both a telescope and signal flags, two-way communication between ship and shore was possible several hours before an incoming vessel reached the docks. The tower was designated a National Historic Landmark and a National Historic Civil Engineering Landmark in 2006.

a historic maritime signal tower at 138 Congress Street in the Munjoy Hill section of Portland, Maine. Built in 1807, it is the only known surviving tower of its type in the United States. Fantastic views of the city and bay!

Step into history with a visit to this round wooden tower, built long ago to get first glimpse of sails on the horizon, heralding another important arrival for the busy port. Docents will fill you in on the many fascinating details of the building and its purpose. Don't miss it! Step up the road afterwards for creative deliciousness at the Blue Spoon, just a block away.
