THE Police Rehabilitation Centre at Flint House near Goring is holding an open day on September 14.
The building on Reading Road celebrated its centenary this year and the charity will be displaying old photographs and documents from throughout its history.
Visitors will be given tours of the property and its 19-acre grounds.
Tea will be served on the terrace afterwards.
The charity’s chairman Daphne Priestley OBE and chief executive Commander Tom McAuslin will be among the guests.
Originally built as a private residence, Flint House regularly opened its grounds to the community in the Twenties and Thirties.
It served as a convalescent home during the Second World War and briefly as a private school in the Sixties.
The Police Rehabilitation Centre bought Flint House in 1985 because its premises in Hove were too small.
Since taking over the Grade II listed building, it has extended it several times.
It now cares for more than 3,500 wounded officers every year.
Those looking to attend the open day must register in advance by August 30.
