This neighbourhood contains London Bridge, Monument station, and King William Street. To the north is Cannon Street connected up to Eastcheap; and Upper and Lower Thames Street to the south. The area is mostly comprised of modern office buildings, interspaced with a few neoclassical designs, particularly near the Monument junction. The area is packed with these medium-height offices, with limited green or open space. At street level, the buildings tend to contain eateries and other chain stores. King William Street leads on to London Bridge (and indeed was constructed for that purpose), connecting Monument and the City in general directly to the Borough area south of the river. Clear bicycle paths are denoted on most of the major thoroughfares in the area.

King William Street had its own underground station from 1890 (when it was the northern terminus of the City and South London Railway, the predecessor of the Northern line) until 1900, when new tunnels were built from Borough, and the line was extended to Moorgate. The station faced east and had sharp curves and steep gradients, and thus was abandoned as the line moved northwards. The old tunnel can still be seen today just after leaving Borough station form the left-hand side of a northbound train. The City and South Railway was the first electric deep-level ‘tube’ line in the world.

James Greathead was born in Grahamstown, South Africa in 1844, arriving in 1859 and worked as a civil engineer. He would design a modified tunnelling shield (the Greathead Shield), improving on the first tunnelling shield developed by Marc Isambard Brunel, which was used to complete the Tower Subway, which ran under the River Thames near the Tower of London. He would later use a similar shield technology to construct the City and South Railway, which ran under King William Street.

1 King William Street was built between 1921 and 1922, designed by William Campbell-Jones and Alex Smithers for the London Assurance Company. Built in the classical style, the façade incorporates details such as giant pilasters and cornices.

Eastcheap derives its name from East and Cheap, the latter meaning market; distinguishing itself from Westcheap, which is today known as Cheapside.
King William Street is a major artery in central London and accordingly is highly congested – from the Monument junction to Southwark Bridge. However, it offers residents and businesses unparalleled access to the south of the river (particularly the Borough and Waterloo areas) as well as to other parts of central London.

33 Central at 33 King William Street is a recently completed development in the area that was funded by Wells Fargo, in a £300m deal to establish a European headquarters in London. Further north, a new entrance to Bank station has recently opened on nearby Cannon Street as part of stationwide renovation works. Above this new entrance will sit a contemporary office block. Taller than originally planned, planners recently gave permission for TFL to add an eighth floor to their plans, with work scheduled to start by the end of 2022.
