Portland Observatory, Maritime signal tower in Munjoy Hill, Portland, US

The Portland Observatory is an octagonal wooden tower on Munjoy Hill that rises 26 meters high with a 10-meter base diameter. The width tapers to about 4.6 meters at the observation deck, while the interior structure includes multiple levels for climbing.

Captain Lemuel Moody built this communication station in 1807 to monitor vessel traffic in Portland Harbor and inform merchants about approaching ships. The building played a key role in tracking merchant shipping and supporting the local economy.

The tower reflects the craftsmanship of shipbuilders who used local Maine white pine and traditional wood joinery to create a sturdy structure. Walking inside, you notice how skilled workers fitted wooden joints and beams together with remarkable precision.

Visitors can climb the stairs to the observation deck and take in views of the harbor and city landscape from above. It is wise to avoid storms or extreme weather, as the top platform is not safe during poor conditions.

The foundation contains 55 tons of rubble stone ballast and a timber grid system that keeps the tower stable against strong coastal winds. This thoughtful foundation design allows the structure to withstand decades of extreme weather conditions.
