+ My Favorites
The Portland Observatory is the last remaining maritime signal tower in the United States. The 86 foot high tower was constructed to make Portland's busy harbor more efficient, as signal flags from the tower told local businessmen when their ships were coming in. The Observatory will be open to explore seven days a week from June 10th to October 9th. Contact Greater Portland Landmarks for exact times.
