Come visit the last remaining maritime signal tower in the US!

The integrity and architectural significance of the Portland Observatory is well documented through its listing as a National Historic Landmark and National Civil Engineering Landmark. However, the tower is so much more than this!

Join a passionate, knowledgeable docent for a 45 minute guided tour where you will be fascinated by Captain Lemuel Moody (the builder) and his family, hear why this place is “NOT A LIGHTHOUSE,” and learn more about the tower’s place in the rich, unique maritime history of Portland (Maine). After climbing 7 stories and 108 stairs, you will be gifted a tremendous view of Casco Bay and her islands! Trust us, the history tours is worth hearing, but you cannot beat the view either!

The Portland Observatory is owned by the City of Portland and operated by Greater Portland Landmarks, a non-profit organization dedicated to the stories of people and places that make Portland a home to visit, work, and live in. Scroll down to learn more about our work!
