Knockturn Alley

Knockturn Alley (a play on the word "nocturnally") is a dark and seedy alleyway leading off from the more savoury Diagon Alley to which Muggles have no access. It is frequented largely by Dark Wizards. Many of the shops in Knockturn Alley are devoted to the Dark Arts; the largest is Borgin & Burkes, which sells sinister and dangerous objects.
