Fratton Park is a football ground in Portsmouth, Portsea Island, England and is the home of Portsmouth F.C. Fratton Park's location on Portsea Island is unique in English professional football, as it is the only professional English football ground not located on the mainland of Great Britain. Fratton Park has been the only home football ground in Portsmouth F.C.'s entire history.
Fratton Park was built in 1899 by Alfred H. Bone, a Portsmouth-based architect, surveyor and a founding director of the football club. The site of Fratton Park was formerly a market garden potato field in a Portsea Island farming village named Milton. By 1904, the village of Milton and the rest of Portsea Island had become part of the borough of Portsmouth.
