The tour leaders at the Portland Observatory were very knowledgeable and kind. We walked up the stairs to one level, paused for some information and a brief look around, then moved up to the next level. The story is wonderful and the view from the top ~ since our day and time were clear ~ was breath-taking.

Named a National Historic Landmark in 2006, the Portland Observatory is the only known remaining historic maritime signal tower in the United States.

No tours were running when we were there but it was fun to stop by anyway. The building is quirky, even from the outside.

i might be spoiled living on Chicago who has a great planetium but this observatory was interesting but small. Almost all the staff was very friend and couls answer all you questions easily. it was a fun afternoon adventure but defantely not a day long event.

It was a very interesting tour and we didn't even get to see the view since the fog was so thick. Would highly recommend to adults. Long tour for young kids
