Portland Observatory

It's not a lighthouse - and it has nothing to do with astronomy!

The Portland Observatory (1807) is the only extant maritime signal station in the United States, and thus a unique architectural icon of maritime shipping and the "Golden Age of Sail." The Portland Observatory was added to the National Register of Historic Places in 1972, and became a National Historic Landmark in 2006. The structure was also awarded the American Society of Civil Engineers Historic Landmark award for excellence in engineering, in 2006.

Sea captain-turned-entrepreneur, Lemuel Moody (1768-1846), ordered construction of this octagonal, 86' high tower to serve as a communication station for Portland's bustling harbor. With his powerful telescope, Moody identified incoming vessels and then signaled merchants with coded signal flags. "Signalizing" allowed merchants ample time to reserve a berth on the wharves, and to hire a crew of stevedores before a vessel docked. This made for efficient unloading of merchant vessels and was an essential part of local commerce.

The Observatory was built at the eastern end of the Portland peninsula on Munjoy Hill, which was a cow pasture at the time. Moody built his home and other buildings near the tower. The complex of buildings was replete with banquet and dance halls as well as a bowling alley. From the time it opened in 1807, it was a tourist attraction.

 

 

 

 


Signal FlagThe tower ceased its "signalizing" operations in 1923, and has been owned by the City of Portland since 1937. In 1936 the Portland Observatory was included in the Historic American Buildings Survey (HABS), and in 1939 the tower was a Works Progress Administration (WPA) project during the New Deal programs of the Great Depression.

Signal FlagIn 1994 it was discovered that years of seeping moisture and an infestation of powder post beetles threatened the structure. Many architectural and historical preservation authorities came together to devise a plan for saving this historic building.

Signal FlagIn 1997 Greater Portland Landmarks (GPL) chartered the Portland Observatory Restoration Trust (PORT) in order to raise funds for the ailing structure's ambitious restoration. More than six hundred donors contributed to PORT, including the City of Portland, corporations, charitable foundations, families, and individuals, as well as students from eleven local elementary schools who gave more than $5,000 through KidsPORT. PORT raised $1.28 million for the 1998-2000 restoration, which returned the building to its former glory.

Signal Flag Currently, Greater Portland Landmarks operates the Observatory as a museum and historic site, offering educational programs and seasonal guided tours. Interpretive exhibits explain the tower's history and preservation. Please note that we provide guided tours only. This is for the safety of visitors and the protection of the building. We regret we cannot allow unsupervised visitations. Please plan to allow one-hour for your tour.
