Since 1807, the Portland Observatory has offered spectacular views of Portland’s busy harbor and served as a beloved symbol of the city’s rich maritime heritage. Named a National Historic Landmark in 2006, the Portland Observatory is the only known remaining historic maritime signal tower in the United States.

The Observatory is closed for the 2015 season. We will see you in May 2016!
