Description

The monument comprises the remains of a multivallate hillfort, which probably dates to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales), and a small medieval chapel. The fort is located on the shore of the Bristol channel with its southern boundary formed by a small sea cliff, and multiple ramparts to the N, E and W. The inner rampart if the largest, standing around 6m high, it forms an arc enclosing the fort interior, which is level and now used as a football pitch. On the NE side of the fort the outer ramparts have been destroyed by housing, but on the NW side there are two further banks separated by ditches, with an outer ditch that now lies largely under the line of the fence surrounding the adjacent paper mill. The outer of these two banks is the highest, around 2.5m maximum, with the middle bank a maximum of around 1m in height. The ditches are around 3m wide and up to 0.8m deep. The entrance to the fort is on the NE side. The site was investigated by Nash-Williams in the 1930s, who discovered the remains of the NE ramparts with V-shaped ditches between. He also identified that the main inner rampart had been built in four phases and had revetment walls on the inner edge. Inside the bank on the NW side he also identified quarry ditches. Finds from the site indicate that it was occupied from the 2nd century BC to the 2nd century AD, and provide tentayive evidence that the Roman army held the fort at around AD 50, presumably to guard the strategic crossing of the river Severn.

The remains of the chapel consist of a chancel arch with a belfry above, a nave and a S porch. The chapel, Holy Trinity Church, is of 12th to 14th century date, with the porch added in the 15th or 16th century. The site is recorded as still being in use in 1560 but was 'decayed' by 1755.

The hillfort is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, building techniques and functional detail.
