London Wall and its gates

ancient defensive wall built by the Romans around Londinium

Bishopsgate was one of the eastern gates in London's former defensive wall. The gate's name is traditionally attributed to Earconwald, who was Bishop of London in the 7th century. It was first built in Roman times and marked the beginning of Ermine Street, the ancient road running from London to York (Eboracum). The gate was rebuilt twice in the 15th and 18th centuries, but was permanently demolished in 1760.

Cripplegate was a gate in the London Wall which once enclosed the City of London, England.

Ludgate was the westernmost gate in London Wall. Of Roman origin, it was rebuilt several times and finally demolished on 30 July 1760. The name survives in Ludgate Hill, an eastward continuation of Fleet Street, Ludgate Circus and Ludgate Square. The gates' materials were sold for £148.

Moorgate was one of the City of London's northern gates in its defensive wall, the last to be built. The gate took its name from the Moorfields, an area of marshy land that lay immediately north of the wall.

Aldersgate is one of the 25 wards of the City of London, with the City forming the historic and financial centre of Greater London, England. It is named after one of the northern gates in the London Wall which once enclosed the City.
