Overview

History & significance

Morlais Castle is a medieval fortification situated in the parish of Merthyr Tydfil in Glamorgan, Wales. The castle was constructed in the early thirteenth century, likely during the 1270s, by the Norman lords of Glamorgan as part of their defensive network across the region. The site comprises a substantial stone keep and bailey works positioned on a prominent hilltop, commanding views over the Merthyr Valley and the approaches to Glamorgan. Though substantially ruined, the surviving masonry demonstrates the castle's original importance as a stronghold, though it was likely abandoned or fell into disrepair by the late medieval period as Norman power in south Wales diminished.
