Portland Observatory
Portland, ME, United States
Built in 1807 and currently a National Historic and Civil Engineering Landmark, the Portland Observatory is the nation’s last remaining ship-to-shore signal tower. Our firm was commissioned to restore the dilapidated timber-framed tower to the period of the nineteenth century. Initially the building’s exterior sheathing was dismantled and the lantern removed to facilitate the assessment of the tower’s timber frame. Using historic photos, graphic documentation, and our HABS level measured drawings, ttl-architects prepared construction documents and oversaw the tower’s restoration. To preserve the historic character of the tower we designed a side walk lift to provide universal access to the ground floor. Inside, new exhibits and a remote live video display was installed to provide views of the harbor to those unable to climb to the top. An official project of the Save America’s Treasure’s Program of the National Trust for Historic Preservation, the restoration was funded with grants from the National Trust and the National Parks Service, as well as funding from ISTEA and the Department of Housing and Urban Development’s HCD program. The project received a National Trust for Historic Preservation Award and a Maine Historic Preservation Honor Award.
