The Trundle is a hillfort from the Iron Age on St Roche's Hill, north of Chichester, England. It is built on the site of a causewayed enclosure, a form of early Neolithic earthwork. Causewayed enclosures were built in England from shortly before 3700 BC until about 3300 BC; their purpose is not known. A chapel dedicated to St Roche was built on the hill around the end of the 14th century; it was in ruins by 1570. The hillfort is still a substantial earthwork (pictured), but the Neolithic site was unknown until 1925. Causewayed enclosures were new to archaeology at the time and an aerial photograph persuaded archaeologist E. Cecil Curwen to excavate the site in 1928 and 1930. These early digs established a construction date of about 500 BC to 100 BC for the hillfort, and proved the existence of the Neolithic site. In 2011 the Gathering Time project used radiocarbon dating to conclude that the Neolithic part of the site was probably constructed no earlier than the mid–4th millennium BC.
