Odiham Castle (also known locally as King John's Castle) is a ruined castle, that is one of only three fortresses built by King John during his reign. The site was possibly chosen by King John because he had visited the area in 1204 and it lay halfway between Windsor and Winchester.
It is reputedly haunted by the sound of an "ancient song" being sung to the notes of a lute. Less reported is the apparition of a singular minstrel that wanders through the ruins, or phantom forms of former prisoners that were held here centuries ago.
