Although the exact locations are not reveled this video shows some pretty creepy photos of abandoned bunkers and underground hideouts around the state!

The YouTube channel 'History of America: Project US' visits and documents abandoned places and US military bases. They found plenty in Maine!

They point out general areas were these places are located but do not give exact locations for safety reasons. But how many of these places did you know about?! We've never seen any!
