Knockturn Alley

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

Knockturn Alley is known for being, as stated by Rubeus Hagrid 'a dodgy place'. While the shops in the Alley are known for dark items, other useful items can be boughten, like flesh-eating slug reppelant.
