The largest city in Britain—larger even than the muggles know. With several magical side streets accessible only to those who know they are there, the city boasts the most commercial magic activity outside of Hogsmeade.

A large, imposing facade marks the entrance to the Ministry, however, the facade is just that; upon entering the building in Hogsmeade or London, you are transported to the atrium of the Ministry of Magic building in London. The main floor, the atrium, is located on the first floor. Gold gilded fire places are pressed up against two of the walls and serve for arrivals and departures. The floor is black and white checkered squares, while the ceiling stretches up so high that one cannot see it. It is a vast blackness and most try not to look at it. Farther down the room is a long hallway which holds several lifts, operated by a person of lower class. The lifts can move forward, backward, right as well as left and are able to reach all the way up to the ninth floor.

Flourish & Blotts Tightly-packed buildings pile high over the narrow cobblestone streets in the hub of Magical London. Though the area is primarily commercial, some magical residents have taken on flats above the myriad shops that line the district. Accessed via the rear of The Leaky Cauldron.

The Jinxed Jackrabbit
Borgin & BurkesA shadier shopping district for the darker soul. Accessible via Diagon Alley.

To enter the premises, one may step through the window of what appears to be a red-bricked, condemned department store called Purge and Dowse, Ltd. The interior, on the other hand, looks exactly as a hospital should. One way one individual can enter the building is speaking to an apparently inanimate dummy in the department store.

Founded by the Crowdy family shortly after the death of Maximilian Crowdy, then Minister of Magic, in 1781. Inaccessible to muggles, the library is located about a block from the Ministry of Magic Headquarters. The first three floors are open to the public, boasting reception and literature, reference texts, and public records, respectively. The subsequent five floors are grouped by subject matter, and accessible only to Ministry employees with the appropriate clearance level, or members of the public who have received permission from the Department of Magical Education for a particular use. Such petitions take from two to ten months to receive word on.

Located in London, The Museum of Magical Miscellany is reachable through a secret door in a regular, muggle museum. Filled with exhibits on everything from Ancient Rome to the muggle riots of 1877, the museum is massive and winding, and has statues, artifacts, and paintings, all related solely to wizarding history. Visitors may berate resident ghosts for historical details if they are so inclined.
