This Christian-themed park was built in the late 1950s and initially thrived as a Connecticut attraction, according to Atlas Obscura. In the mid-80s the park’s owner closed it down to work on expanding the site, but he died in 1986 and it was never reopened. Now long abandoned, Holy Land USA has been widely vandalized and was even the site of a murder in 2010.
