This is what we found on Wikipedia regarding the Strawberry Field Liverpool:

Strawberry Field is a visitor attraction and training centre in the Liverpool suburb of Woolton that is owned and operated by the Salvation Army. It operated as a children's home between 1936 and 2005. The house and grounds had originally been built as a private residence in the Victorian era, before being acquired by the Salvation Army in the 1930s. The house was demolished in 1973 due to structural problems and replaced with purpose-built units. After being closed as a children's home, the site has continued to be used by the Salvation Army for other purposes.

The location gained worldwide fame following the release of the Beatles' 1967 single "Strawberry Fields Forever". The song's writer, John Lennon, had grown up nearby and played in the grounds of the home as a child. In time, the old red-painted entrance gates on Beaconsfield Road became a place of pilgrimage for Beatles fans. In 2019, Strawberry Field was opened to the public for the first time, with an exhibition on its history, cafe, and shop, alongside a training centre for young people with special educational needs.

The gates were stolen on 11 May 2000, allegedly by two men in a transit van. The gates were sold to an unsuspecting antiques dealer who never realised they were the actual gates from Strawberry Field. He returned them to the police upon request, and they now stand in the grounds of Strawberry Field.
