The Sentinel

Sentinel is a 16-metre-high sculpture by Tim Tolkien, installed upon Spitfire Island, a roundabout at the intersection of the Chester Road and the A47 Fort Parkway at the entrance to the Castle Vale estate in Birmingham, England.

It is near Junction 5 of the M6 motorway and the present day Jaguar Cars plant. It shows three Supermarine Spitfires peeling off up into the air in different directions. The half-scale Spitfires are made of aluminium, with curving steel supporting beams which act as vapour trails. It captures the dynamics of the Spitfire in flight and commemorates the nearby Castle Bromwich factory where most of Britain's wartime Spitfires were built.
