Knockturn Alley

Knockturn Alley is a shopping area off Diagon Alley in London, England. It is filled with lots of shops devoted to the Dark Arts, including Borgin and Burkes, which specializes in objects that have curious and strong magical properties. Usually, unusual, dangerous and scary people walk around here. When Tom Riddle left Hogwarts, he worked at Borgin and Burkes.

Harry Potter first entered Knockturn Alley in 1992 when using Floo Powder at The Burrow. He ended up at Borgin and Burkes when he didn't say "Diagon Alley" clearly enough when trying to travel by Floo Powder from the Burrow. He ran into Rubeus Hagrid outside the shop. Hagrid, who was getting Flesh-Eating Slug Repellent in Knockturn Alley, told Harry that he shouldn't be hanging around in such a "dodgy place."

Harry's next visit to the alley was in 1966, when he, Ron, and Hermione followed Draco Malfoy, suspecting him being a Death Eater. Draco let several Death Eaters into Hogwarts through the Vanishing Cabinet in Borgin and Burkes at the end of the 1996-1997 school year.
