Stuyvesant's Alley is the wizarding district of New York City, located somewhere in Lower Manhattan. It has existed since the late 17th century, just after the International Statute of Secrecy was adopted. Prior to that time, magic folk had mingled with muggle settlers in New Netherland.
Connecting directly to Stuyvesant's is the shadowy Duyvell's Alley, where shops specializing in dark magic have been segregated. Duyvell's Alley has its own Wunderground station, which opens directly onto the street.
