Beginning in the west, where the City borders Westminster, the boundary crosses the Victoria Embankment from the Thames, passes to the west of Middle Temple, then turns for a short distance along Strand and then north up Chancery Lane, where it borders Camden. It turns east along Holborn to Holborn Circus, and then goes north east to Charterhouse Street. As it crosses Farringdon Road it becomes the boundary with Islington. It continues to Aldersgate, goes north, and turns east into some back streets soon after Aldersgate becomes Goswell Road, since 1994 embracing all of the Corporation's Golden Lane Estate. Here, at Baltic Street West, is the most northerly extent. The boundary includes all of the Barbican Estate and continues east along Ropemaker Street and its continuation on the other side of Moorgate, becomes South Place. It goes north, reaching the border with Hackney, then east, north, east on back streets, with Worship Street forming a northern boundary, so as to include the Broadgate estate. The boundary then turns south at Norton Folgate and becomes the border with Tower Hamlets. It continues south into Bishopsgate, and takes some backstreets to Middlesex Street (Petticoat Lane) where it continues south-east then south. It then turns south-west, crossing the Minories so as to exclude the Tower of London, and then reaches the river. It then runs up the centre of the Thames, with the exception that Blackfriars Bridge falls within the City; the City controls London Bridge (as part of Bridge ward) but only half of the river underneath it, a feature which is unique in British local administration.
