Number Twelve, Grimmauld Place

Number Twelve, Grimmauld Place is the Black family house in London, hidden by a Fidelius Charm once Dumbledore is Secret-Keeper and later under the trio’s keeping. It is the headquarters of the Order of the Phoenix in the fifth book. Kreacher keeps it, the curtains shout, and a locket Horcrux is found among the rubbish.
