Knowle Haven

Region: South East

This site, which was acquired by the Land Trust in 2015, spans a 3.5-hectare field and 1.5 miles of Mayles Lane. Knowle Haven was previously used for grazing, and has great potential to form new habitats, enhance public access and host community and educational events.

The Land Trust plans to connect the new and old communities of Fareham, Funtley and Knowle through the creation of a community woodland, or similar scheme, and manage the land as a resource for wildlife and the community.


Mayles Lane, Knowle, Fareham, PO15 6DT

Site size: 5 hectares

Visitor Information


The land was formerly the site of Hampshire County Lunatic Asylum, which opened in 1852 and then went through a number of extensions to cover a 100-acre site known as Knowle Farm. In the 1950s it reached its peak with 2,000 patients housed.

The Asylum was renamed Knowle Mental Hospital in 1923, and then Knowle Hospital in 1948, before finally closing in 1996.

Berkeley Homes purchased a large part of the hospital site and started development of Knowle Village in 2000, securing approval to deliver 500 homes within 53 acres of the former hospital site.
