Napsbury Park is on the site of Napsbury Hospital, a large mental hospital that existed from 1898 to 1998, with at least one building still in use at least to 2002. The site was listed as a Grade II Historic Park and Garden in 2001 and since then has undergone redevelopment into a residential area.
Many of the old buildings were renovated into residential space, some were torn down and others have been neglected and are in a severe state. The ones renovated are good examples of how Napsbury Hospital once appeared. A number of homes are owned by Arsenal FC and Watford FC football players, since practice fields are just outside London Colney.
