The pool in this earthwork is one of the places here King Arthur ‘s sword Excalibur is said to have been thrown (cf Dozmary Pool on Bodmin Moor). Ghostly galloping hooves and wailing voices are rumoured at Trent barrow, following an incident when a coach and horses with all the passengers aboard drove into the pool. This site is only a few miles from South Cadbury Castle which is often believed to be the site of Camelot.
Highly mysterious! How old is Trent Barrow?
