St. Mungo's

The entrance to St. Mungo's is concealed behind an abandoned red-brick London department store called Purge and Dowse, Ltd. on a Muggle street. Unlike, say, the Leaky Cauldron, St. Mungo's is visible to passing Muggles, who merely believe the sign on the front that the store is "Closed for Refurbishment." In the front window, a dummy dressed in outdated styles serves as the gatekeeper; wizards wanting to enter do so by talking to the dummy, and then walking straight through the window
