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.

  • When your in Portland you have to go . SO glad we got to go on their last day open for the season . The history about it I found very interesting. The views from the top are fantastic!  more »
  • It’s only by guided tour and locks you into 45 minutes and lots of stairs, but still very enjoyable if even a bit TOO much tour information before you get to see the view  more »

  • Beautiful interior! I loved visiting this cafe and would recommend for others to try it out. My mocha was very good and not to sweet. I went around 4pm, but by then most food options had run out. Get there early if you would like to grab one of their goodies!!
  • 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.
