Holborn

Holborn is an area of central London and also the name of the area's principal street, known as High Holborn between St. Giles's High Street and Gray's Inn Road (the junction being roughly where Holborn Bar—the entrance to the City of London—once was) and then Holborn Viaduct between Holborn Circus and Newgate Street. Since boundary changes in 1994, the street runs along the boundary between the London Borough of Camden and the City of London; previously the boundary was less obvious in the area and crossed the street at Holborn Bar.
