There is a group of five Bronze Age tumuli at the summit of The Garth.
Two Iron Age hillfort and enclosure sites have been identified at Craig y Parc and Llwyn da Ddu.

During quarrying of the Lesser Garth in 1965 a hoard of Iron Age metal work was discovered. The terret ring was made in the first century BC and is one of the largest and finest harness fittings of this period found in Britain. This terret was found by Albert Burke, a worker at Steetley Quarry, on the Lesser Garth. It was given to the National Museum of Wales by Mr Lewis Edwards who realised its antiquity.
It measures about 5.5inches across and is a 'terret' (a loop through which the reins of a chariot are passed). It dates from the Iron Age and is made of bronze and finely decorated with enamels.
