Moorgate was one of the City of London, England'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.

This resulted in systems, known as Moorgate control, being installed on the Underground in order to stop trains at dead-ends.

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 marshy open space known as Moorfields, it was not one of the larger or more important of the city gates.

It was replaced with a newer and larger structure located farther to the west, which included a wooden gate to be shut at night.

The gardens in the centre of the circus occupy a 5,000-square-metre (1.2-acre) plot enclosed by railings, and include the lawn of the City of London Bowls Club.

A 36 m shaft under the building incorporates part of Crossrail's new station and ticket hall serving Liverpool Street.

These include a 43-storey, 140 m residential skyscraper at Milton Court (The Heron), that is taller than CityPoint, and a 90 m office tower at Ropemaker Place is also being developed by British Land, with construction already underway.
