Holy Land USA was once an 18 acre (7.2 hectares) theme park in Waterbury, Connecticut, that at its peak in the 1960s and ’70s saw upwards of 40,000 visitors per year. It was closed for renovation in 1984; its owner, John Greco, died in 1986, and nobody has been sure what to do with it since. The property has been watched over by a group of nuns in the intervening decades, while it deteriorates more and more, and just gets more and more disturbing.
As if the crumbling statues, dark and still structures and obvious vandalism don’t get your “let’s get the hell out of here” meter in the red, there’s also the fact that a teenager was murdered on these deserted grounds in 2010. While police reports have shown instances of trespassing dropping, that really just means there are fewer people around, making the place even more isolated and terrifying.
