Friends of Fort Knox

Fort Knox and the Penobscot Narrows Observatory
Fort Knox Historic Site and the Penobscot Narrows Bridge Observatory are open:
– 9am to 5pm in May/June/September/October

– 9am to 6pm in July and August

The Fort itself remains open an hour later than the observatory 

Grounds are open until sunset, weather-depending.

Pets are welcome everywhere (except in the Observatory) if on a 4′-6′ leash, cleaned up after, and not a nuisance to other guests. Pets are not allowed to be unattended in your vehicle. 

The Fort Knox Historic Site features one of the best-preserved examples of coastal defense fortifications constructed in the mid-1800s. It is America’s first fort named after Major General Henry Knox.  Volunteer docents (experts) provide free interpretive tours (when available) from May 1st through October 31st, between 11 am to 3 pm.  The PNO is the tallest bridge observatory open to the public in the world.  Visitors to the observatory ride Maine’s fastest elevator up 420′ feet for breathtaking 360-degree views of the Penobscot Bay area.
