Observation Deck · Hidden Gem · Landmark
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 in 2006; it is now managed by Greater Portland Landmarks, a local historic preservation nonprofit. It is open to the public as a museum.

  • Historic place. Lot to learn from the guide. Nice people around. We really liked the girl on the top floor who explained everything in detail and took our family photo. Great experience.
