Bokerley Dyke

Bokerley Dyke is a linear earthwork 5.75 km long on Cranborne Chase in Dorset, running along the county border with Hampshire between Woodyates and Martin. It may have originated in the Bronze Age as a political boundary, and was cut through by the Roman road Ackling Dyke in the 1st century AD. In the 4th century it was remodelled and the Roman road blocked, dated by a coin of Valens to shortly after 364 AD, possibly in response to the Great Conspiracy of 367-368 AD. It was excavated by Augustus Pitt Rivers between 1888 and 1891 and is a Scheduled Monument.
