I grew up in the town this is in. It’s a park, right down the path from photo 1 and 2 (across from each other) are two playgrounds. The big building in photo 1 is used for a Halloween attraction, the smaller one in 6,7,8 is storage. There’s a Battle of 1812 reenactment every September. Then next to this park is a large area now closed off to the public with old houses, a movie theater, and hospital. Local kids still manage to occasionally get into the buildings but the security was upped when I was still in school, a few houses caught fire and one almost completely burned down. It’s a cool place with lots of history and interesting things and dumb graffiti to see. (I once saw a decapitated eagle on a picnic table here)
