Guards Club Park was created by Maidenhead Civic Society to commemorate the Silver Jubilee in 1977 and has been maintained by the Royal Borough of Windsor and Maidenhead since 1980.
Originally, the Brigade of Guards Club provided recreation for the officers who were stationed at Windsor and Pirbright. A large club house contained a ballroom and in its Victorian heyday, the Guards Club ball attracted debutantes and royalty. Outside there was a swimming pool. croquet lawn and on the island a boathouse.
The unique ornate footbridge, built around 1865, led to the club boathouse on the island. The bridge was rescued by the Maidenhead Civic Society in 1976 and was last renovated in 1997. There is little remaining of the boathouse but the spire now covers the shelter in the park. ...
Through its work on the island, the Royal Borough is helping to enhance the nature conservation value along the River Thames. The island is home to varied wildlife providing nesting sites for swans, moorhen and coot.
