Fort Popham State Historic Site in Phippsburg, Maine is a fine example of a civil war era fort built during the the Third System of fortifications which began in 1861. The ruined fort is great fun to explore and run about with towers and dark tunnels. A great place to spend an hour either before or after heading towards the beach at Popham Beach State Park just two miles up the road.
All kinds of informative signage if you want to learn something while exploring.
Watch Alex’s video to see how much a young child loves exploring the old fort.
“The fort was built a long time ago way before I was even born” – Alex (HaHa)
