The secluded Magna Carta Island, where it is believed King John sealed the great charter, is on the market through Sotheby’s for a staggering £3,950,000- just in time for the charter's 800th anniversary next year.
The island is a 3.72-acre plot in the River Thames, where it is believed King John used the protection of a circle of walnut trees and the curve of the river to keep enemy bows out of range.
The property is located opposite Runnymede Meadow, where the Magna Carta memorial and John F Kennedy memorials lie.
The Grade II-listed property has a charter room, housing the stone where it is thought the charter was sealed, surrounded by the crest of King John and the 25 barons elected to keep the Magna Carta safe, hanging on the walls.
The house was built by George Simon Harcourt, lord of the manor and the sheriff of the county in 1834 and is connected to the mainland via a small bridge.
In the garden, there is a tree which was planted by the Queen in 1974 to mark her visit to the historic site during her Royal Progress from Windsor, as well as an outdoor swimming pool.
The six-bedroom property includes a dining room to seat 16 people, with wood panelling and a grand fireplace, as well as an outside cottage which has has a reception room, kitchen/breakfast room, two bedrooms and a bathroom.
