Originally called Park Row it is one of Gotham's most infamous locations. Crime Alley is said to be the "birth" of Batman and is often spoken in Bruce's origin. He had lost his parents, Thomasand Martha, in a shooting by a crook named Joe Chill who shot them point blank. It is said that after the gunning of the Wayne's, Gotham started to sink into a wave of crime. Bruce is known to visit this area often every year, leaves two roses in spot in memoriam. Recently Dick went with Damian to honor this tradition.
Some depictions have the murder take place in a back alley, though most depict a scene under a street light on the street corner. The site hosts the movie theater Bruce attended before the shooting.
Years later, Batman ran into Jason Todd trying to lift tires off the Batmobile on one of his visits to the area and subsequently placed him in a local orphanage. He later discovered however, that it was being run as a training ground for child thieves which Batman had to take down.
This is the only place in Gotham that has remained intact through the years and rebuildings, thanks to Bruce's influence.
