Excavations at Cefn Cwmwd prior to the development of the A55 road scheme revealed part of a Bronze Age cremation cemetery and extensive remains of a settlement occupied from the late prehistoric period into the early post-Roman period.
Archaeological assessment and excavation prior to the construction of the A55, a dual-carriageway between Bangor and Holyhead provided the opportunity to examine 32km corridor across Anglesy, one of the richest archaeological landscapes in Britain.
At Cefn Du gullies and pits from the early and late Neolithic period were excavated along with a farmstead occupied from the late Iron age to the late 2nd Century AD. The terracing of these structures into the south-facing hill slope provided favourable conditions for the survival of the northern half of the structures.
Excavations at Cefn Cwmwd revealed part of a Bronze Age cremation cemetery and extensive remains of a settlement occupied from the late prehistoric period into the early post-Roman period. The extent and complexity of the Romano-British settlement was entirely unexpected revealing the remains of twelve buildings and pit groups dating from the later 1st century to the mid 4th century AD.
All work was completed on time and the results published in a single volume ‘A corridor through time’.
