Eastern State Penitentiary
This place opened in 1839 and housed some pretty famous criminals including Al Capone and bank robber Willie Sutton. The craziest story I heard that day is about a dog named Pep that was given a life sentence for killing the governor's wife's beloved cat. The cutest black lab but even in his mugshot (yep, he had a mugshot) he looked guilty as sin.

Who knew there was such an interesting spot right here in Philly!
