In which English river will you find the Magna Carta Island?

Magna Carta Island is an island in the River Thames in England, on the reach above Bell Weir Lock. It is in Berkshire across the river from the water-meadows at Runnymede. The island was transferred from Buckinghamshire to Berkshire in 1974.

The island is one of several contenders for being the place where, in 1215, King John sealed the Magna Carta. Whilst the charter itself indicates Runnymede by name, it is possible the island may have been considered part of Runnymede at the time.

The island has a Grade II-listed house, a cottage, outdoor swimming pool and mooring for a boat. There is a small bridge that connects the 3.72 acre (1.5 hectare) island to the mainland. The house was built by George Simon Harcourt, Lord of the Manor and the Sheriff of the County in 1834.

A stone, on which it has been claimed the charter was signed, lies today in a specially-built Charter Room which forms part of the main house. Its walls are hung with the crest of King John and those of the 25 barons elected to keep the Magna Carta safe, including Richard de Montfichet who was the owner of the island , which was part of the Manor of Wraysbury.
