In London, the Moorfields were one of the last pieces of open land in the City of London, near the Moorgate. The fields were divided into three areas, the Moorfields proper, just north of Bethlem Hospital, and inside the City boundaries, and Middle and Upper Moorfields to the north. The headwaters of the Walbrook formed much of the eastern boundary.
After the Great Fire of London in 1666, refugees from the fire evacuated to Moorfields and set up temporary camps there. King Charles II of England encouraged the dispossessed to move on and leave London, but it is unknown how many newly impoverished and displaced persons instead settled in the Moorfields area. In the early 18th century, Moorfields was the site of sporadic open-air markets, shows, and vendors/auctions. Additionally, the homes near and within Moorfields were places of the poor, and the area had a reputation for harbouring highwaymen, as well as brothels and public cruising areas for gay men.James Dalton and Jack Sheppard both retreated to Moorfields when in hiding from the law.
Much of Moorfields was developed in 1777, when Finsbury Square was developed; the remainder succumbed within the next few decades, notably when Moorfields proper was replaced by the modern Finsbury Circus in 1812. Until that time the fields separated the western and eastern growth of London beyond the city wall - with the eastern extension being better known as the East End.
