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 earliest descriptions of Moorgate date from the early 15th century, where it was described as only a postern in the London city wall. Located between Bishopsgate and Cripplegate and leading to a moor known as Moorfields, it was not one of the larger or more important of the city gates.
The contemporary street of Moorgate runs north from Princes Street and Lothbury at the back of the Bank of England, across the road named London Wall and the location of the old gate, and then continues north. It is located inside the EC2 postal district.
