The Gaveston's Cross monument is located on in the trees at Blacklow Hill, marking the spot where Piers Gaveston, favourite of King Edward II, was beheaded in 1312. A ghostly procession has been reported walking down Blacklow Hill, but the most common reported phenomena is the sound of bells tinkling. It is claimed that Gaveston's execution procession was ornately decorated as a way of humiliating him and his love of finery.
