Twmbarlwm, Iron Age hillfort and Norman castle site in Risca, Great Britain
Twmbarlwm is a hilltop site with fortification remains on its peak that rises 419 meters above the surrounding landscape. The distinctive mound, known locally as the Twmp, shows traces of occupation and defenses from two separate periods in history.
The site was first built as a fort by the Silures tribe during the Iron Age, then later transformed by Norman settlers. This shift from a tribal stronghold to a medieval fortress shows how the purpose of this hilltop changed over the centuries.
The summit draws visitors who come for its connection to long-standing walking traditions in the area. Annual Good Friday walks show how this place remains active in the local community's identity.
Several walking paths lead up from the car park below to the summit, with the shortest route taking about half a mile through hillside trails. The paths are clearly marked and offer different options for various levels of fitness and experience.
The hill is connected in local stories to treasure and mysterious bee swarms that supposedly guard the summit according to old tales. These folk legends give the place a legendary reputation that remains known among older residents today.
