Greater Portland Landmarks Inc

The observatory - landmarks operates the portland observatory (1807), a national historic landmark, as a historic site attracting approximately 20,000 visitors annually. The observatory is the last remaining historic maritime signal tower in the country. It was used to sight incoming ships to portland harbor, using a powerful telescope at the top, and flags were flown to indicate ships coming into port. Today the observatory retains its original appearance and features interpretive exhibits and stunning views.
