Ponter's Ball Dyke

Ponter's Ball Dyke is a linear earthwork located near Glastonbury in Somerset [1]. It crosses, at right angles, an ancient road that continues on to the former island of dry land in the Somerset levels surrounding Glastonbury Tor [1]. It consists of an embankment with a ditch on the east side [1]. It is built across the ridge of land between Glastonbury and West Pennard [1]. Both ends of the ditch and dyke disappear into moorland, formerly swamps [1]. The current visible remains extend to just over 1 kilometre [1]. The gap where the road runs through the dyke is staggered, suggesting that the gap is original [1].
