A Storied Summit with Iron Age Roots

Twmbarlwm stands as a prominent Iron Age hillfort perched on the ridge of Mynydd Henllys, or Old Court Mountain. This ancient site was likely a significant tribal center, with its name referencing a 'Llys' or court within the fort. Later, the Normans constructed a motte and bailey castle atop the hill, layering medieval history onto the prehistoric landscape. Near the summit lies an Early Bronze Age cairn, steeped in local legend, including tales of a buried giant possibly linked to Bran from the Mabinogion and guarded by swarms of bees—a mystical aura that adds to the hill’s allure.

The hill’s elevated position offers stunning sunrise and sunset opportunities, drawing photographers and nature lovers eager to capture the sweeping landscapes.
