In 1888, I the Birmingham Society for the Preservation of Open Spaces purchased Rednal Hill and handed it to the city in trust. It also arranged for Pinfield Wood and Bilberry Hill to be leased on a peppercorn (nominal) rent. Birmingham City Council finally purchased Cofton Hill, Lickey Warren and Pinfield Wood outright in 1920. With the eventual purchase of the Rose Hill Estate from the Cadbury family in 1923, free public access was finally restored to the entire hills.
