We are proud to offer unique tours of Portland’s history and built environment through the lens of historic preservation. In addition to our tours of the Portland Observatory we have two other regular tours: The US Custom House and Homes of Portland's Golden Age. We frequently add special, in-depth tours focusing on areas or topics of Greater Portland that need their stories told.  Check our events page to see if we have any coming up.  Sign up for our email list to never miss one again.

Custom House Tours


With its magnificent architecture in the heart of a bustling seaport, The Custom House was recently restored to its 1872 glory.  The building has been closed to the public since 2001 except through this special 30 minute guided tour. Come see the space a young United States of America created to impress merchants from abroad as they came into Portland, one of the country's biggest, busiest and vital harbors at the time.
