Institution description
Founded in 1964, Greater Portland Landmarks' mission is to ensure that Greater Portland preserves its sense of place for all and builds vibrant, sustainable neighborhoods and communities for the future.
Greater Portland Landmarks manages the Portland Observatory tower, located off Congress Street in the historic Munjoy Hill neighborhood of Portland. Built in 1807, the structure is the only remaining historic maritime signal station in the United States. It was added to the National Register of Historic Places in 1972 and became both a National Historic Landmark and National Civil Engineering Landmark in 2006. A visit to the Portland Observatory offers breathtaking views of Portland Harbor and guided history tour.
