Timber Framed Structure, 1807
In the distance to the east, at the top of Munjoy Hill, stands the Portland Observatory, a prominent landmark visible from points throughout the city. Captain Lemuel Moody organized the construction of the signal tower in 1807. Ships in distress could be sighted from it telescope. Color coded flags were flown from the tower to alert ship owners that their vessels were entering the harbor. While radio and radar have replaced the maritime functions of the tower, it still offers a panoramic view of Portland and Casco Bay. The tower stands 221 feet above sea level. It is open to the public during Memorial Day weekend-Columbus Day.
