Grove Hall Park is a 1.19 ha public park in Tower Hamlets, East London. It includes play areas, a ball games area, and a small walled memorial garden. Grove Hall Park was opened as a public park in 1909 following its purchase by the local authority in an auction in 1906. Previously the land had been in the possession of the Byas family, who had established Grove Hall Private Lunatic Asylum on the plot in 1820. This establishment primarily catered for ex-servicemen and was featured in Charles Dickens' novel Nicholas Nickleby (1839). In 1878 it was the largest asylum in London with capacity for 443 inmates.
