The Portland Observatory is 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. 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; it is now managed by Greater Portland Landmarks, a local historic preservation nonprofit. It is open to the public as a museum.

  • Probably should make reservations online beforehand, but we did not realize this. They did happen to have an opening when we stopped by to see it and we were able to get a tour. The tour lasted about an hour and we learned lots of history about this cool place that isn’t a lighthouse, but is built and looks like one. Once at the top there are some awesome views of Portland in every direction you look.
  • This was a great little tour while in Portland. Our tour guide was very knowledgeable and her stories captivating. And the view from the top was pretty spectacular. You can see all over the city of Portland, the inner harbor, out to Porand Head Light, and in the other direction, the White Mountains in New Hampshire.
