10. Andy Warhol’s Townhouse 57 East 66th Street


Warhol bought the Upper East Side townhouse at 57 East 66th Street in 1974 and lived there with his boyfriend Jed Johnson until his death. According to Curbed, after Warhol passed away, executors found a secret trap door in the master bedroom. Since then the 1910 townhouse has also been the home of MTV President Tom Freston and was last listed on the market in 2008 for $35 million.
