Definitely one of the most chilling abandoned sites we've seen lately, the Marlboro Psychiatric Hospital in New Jersey has drawn many urban explorers, including photographer J. Phillip O'Brien.
O'Brien's photos, which he compiled in this Flickr gallery, are also being featured at the blog Gothamist.
Founded in 1931, the Marlboro Hospital has a dark and disturbing history, which includes an unexplained illness that struck 131 patients, four of whom died as a result.
Before the facility was finally shut down in 1998, many patients had died within the grounds... and some disappeared without a trace.
The crumbling gothic structure itself is tucked away in a dense forest, which now seems to be devouring it.
As if that weren't spooky enough, apparently the aura of death that surrounds the main building has attracted families of vultures, who have taken up residence in the upper rooms.
Tales of hauntings are also common to the area, as well as the legend of a homicidal farmer who lives in a slaughterhouse on the grounds. A group of wanted criminals even used it as a hideout earlier this year (they were finally caught).
