Moorgate

Moorgate was a postern in the London Wall originally built by the Romans. It was turned into a gate in the 15th century. Though the gate was demolished in 1762, the name survives as a major street in the City of London. The street connects the City to the London Boroughs of Islington and Hackney, and was constructed around 1846 as one of the new approaches to London Bridge.

The name "Moorgate" derives from the surrounding area of Moorfields, which was one of the last pieces of open land in the City. Today this region is a financial centre, and is home to several investment banks. The street also showcases historic and contemporary office buildings.
