Caerau Hillfort

Caerau Hillfort 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 [1][2]. It is the largest Iron Age site of its type in south Wales and also one of the largest in Great Britain [1][2]. 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 [1]. The site is a Scheduled Ancient Monument [3].
