Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of an Iron Age hill fort measuring some 120m by 64m, occupying a rocky knoll and defended by a double rampart best preserved on the W and E sides. The ramparts make use of natural outcrops and shelves, and these are supplemented by artificial banks of earth.

The hillfort was located to control the valley of the Afon Llynfi where it debouches onto the coastal plain. Significant views are therefore along the Afon Llynfi Valley to the east, and westward towards the sea in an arc from north-west to south-west.

The monument 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.
