The name of this street is self-explanatory – it follows the line of part of the wall that once surrounded the City of London, of which only fragments now remain.
The wall dates from as far back as Roman times and this street – which runs from the intersection with Aldersgate Street to the west to Old Broad Street in the east – broadly follows the course of its northern edge.

The road was re-laid out – it features dual carriageways at the east and west ends – after the area was devastated by bombing during World War II.
A roundabout at the western end of London Wall – named the Rotunda – provides a link with Aldersgate Street, which runs perpendicular, and in the centre was built the Museum of London (which is now being relocated to West Smithfield).

The western end of the street, part of which is straddled by the hulking early 1990s building known as Alban Gate, has until recent years also featured a series of raised walkways which were part of the post war redevelopment of the area (and partly integrated with office buildings).
Known as ‘pedways’, some of them are now in the process of being replaced with a more modern take on the idea (such as can be seen at London Wall Place).

The street features a number of remnants of the actual wall along its length including the remains of a Roman gate close to the western end (on the street’s north side, it’s known as Bastion 14) and in St Alphage Gardens (St Alphage, London Wall is one of several now lost churches along the street – St Olave, Silver Street is another).
Close to the eastern end of the street is the church of All Hallows-on-the-Wall which dates from 1767 (replacing an earlier church that had survived the Great Fire of London).
Other prominent buildings on London Wall include the Brewer’s Hall, the Carpenter’s Hall and the Plaisterer’s Hall.
