Knockturn Alley
Knockturn Alley is described in the novels as a dark and seedy alleyway diagonal to Diagon Alley. Many of the shops in Knockturn Alley, such as Borgin and Burkes, are devoted to the Dark Arts. Objects that have appeared in Borgin and Burkes include a cursed opal necklace, a Hand of Glory, and a Vanishing Cabinet which is used by Draco Malfoy to infiltrate Hogwarts in Half-Blood Prince. Voldemort worked at Borgin and Burkes briefly during the 1940s. The shop is owned by Caractacus Burke and Mr. Borgin, though Mr. Borgin is the only owner to appear in the novels and films.
