Ludgate Circus is a road junction in the City of London. Despite the name, it's a crossroads and not a roundabout. To the east, Ludgate Hill rises toward St Paul's Cathedral. To the west, Fleet Street leads off toward Westminster. Farringdon Street runs northward under Holborn Viaduct, and New Bridge Street leads due south to Blackfriars Bridge. The Circus and the roads north and south lie on the course of the now-hidden Fleet River, which gives its name to Fleet Street.

On the south-east corner is a branch of Waterstone's, incorporating a Coffee Republic. On the north-east corner is the Old King Lud pub. And behind the buildings to the south-west is the wedding cake spire of St Bride's, Fleet Street.
