It was built in the early 19th century and was London`s hay and straw market for a hundred years until the late 1920s. An arm of the Regent`s Canal was built to the market. The market was surrounded by modest housing, and in the early 20th century became an artistic community. The original houses were demolished during and after the Second World War and it is now a housing estate, known as Regent`s Park Estate.
