30 minute guided tour of the US Custom House (1868). Located at 312 Fore Street, Portland, this GSA owned building underwent a massive restoration from 2010-2013, and has been closed to the public since 2001.
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 will re-open for the 2015 tour season on Saturday, May 23, 2015.
