Caerau Hillfort ((ウェールズ語:Bryngaer Caerau)) is a large triangular multivallate Iron Age hillfort, built on a previously occupied Neolithic site, occupying the western tip of an extensive ridge-top plateau in the western suburbs of Caerau and Ely, Cardiff, Wales. It is the largest Iron Age site of its type in south Wales and also one of the largest in Great Britain.〔(【引用サイトリンク】publisher= Channel 4 )〕 The old parish church, St Mary’s, and a small ringwork, almost certainly a medieval castle site probably contemporary with the church, stand within the hillfort on the north-eastern side. ==The hillfort== Caerau Hillfort is the third largest Iron Age hillfort in Glamorgan,〔RCAHMW, 1976. An Inventory of the Ancient Monuments in Glamorgan Vol I: Pre-Norman Part II: The Iron Age and Roman Occupation. Cardiff: HMSO.〕 enclosing 51,000 m², and is surrounded by housing and the A4232. It was once a stronghold of the powerful Silurian tribe who inhabited this part of Wales before the arrival of the Romans. Excavations in 2013-2014 revealed evidence of the site's occupation back to the early Neolithic. Finds included flint tools and weapons dating to 5550 years before present (BP).〔 The steep north and south slopes of the ridge are both fortified by three massive ramparts with accompanying ditches, although these are hidden beneath trees and scrub. On the east side the hillfort defences appear to have been reduced to two ramparts in the north and one in south. There seem to have been two entrances to the hillfort, one in the middle of the east side and one west of the south corner. At the east entrance the ramparts curve round to command the approach, but there is no corresponding in turn at the south entrance. An apex in the north-west of the hillfort may be a third entrance, but it has been heavily eroded by water flowing from a spring. The interior, now pasture, was cultivated in the past, and the characteristic traces of rig and furrow agriculture can be seen on aerial photographs. It is traversed by two earthworks which may be old field boundaries, or even the remains of a smaller, earlier hillfort or even a Neolithic causewayed enclosure. Excavations during Channel 4's ''Time Team'' series in April 2012 showed the hillfort's occupation began about 2550 BP.〔 Iron Age and Romano-British pottery as well as a single fragment of a mortarium (1st century AD Roman pouring vessel) have been found from an area north-west of the southern entrance.〔Jarvis, P.H. 1965.
