The island’s name derives from the story that Oliver Cromwell once took refuge here but there is almost certainly no truth in this. It was called Strand Ayt until a century after the Civil War, by which time the myth had arisen that Cromwell had used the Bull’s Head in Strand on the Green as an inter­mittent headquarters. The story was further embel­lished with suggestions of a secret tunnel connecting the inn and the island, allegedly constructed to help Catholic priests escape Protestant persecutors.

From the late 18th century Oliver’s Island had a kind of tollbooth, a wooden structure shaped like a small castle, which levied charges on passing craft to fund improvements to the river’s navig­ability. A barge was moored alongside, from which the tolls were taken. By 1865 there was a smithy and barges were built and repaired here. In 1909 the Thames Conservancy assigned Oliver’s Island to the Port of London Authority (PLA), which used it as a storage depot and as a wharf for derelict vessels.

In 1958 the residents of Strand on the Green formed an amenity group for their locality, which also took an interest in conser­vation on the island.

The Strand on the Green Association was at the forefront of a successful campaign of resistance when the PLA tried to sell the island in 1971. The smithy was demolished in 1990. The thickly wooded island is now a haven for herons, cormorants and Canada geese. Efforts have been made to control non-​​native tree and bird species.
