Beeston Castle is a former Royal castle in Beeston, Cheshire, England (grid reference SJ537593), perched on a rocky sandstone crag 350 feet (110 m) above the Cheshire Plain. It was built in the 1220s by Ranulf de Blondeville, 6th Earl of Chester, (1170 – 1232), on his return from the Crusades. In 1237, Henry III took over the ownership of Beeston, and it was kept in good repair until the 16th century, when it was considered to be of no further military use, although it was pressed into service again in 1643, during the English Civil War. The castle was slighted (partly demolished) in 1646, in accordance with Cromwell’s destruction order, to prevent its further use as a stronghold. During the 18th century the site was used as a quarry.
It is rumoured that treasure belonging to Richard II lies undiscovered in the castle grounds, but the many searches that have been carried out have failed to find any trace of it. The castle, now in ruins, is a Grade I listed building and a Scheduled Ancient Monument, owned by English Heritage.
