Llansteffan Castle, perched on a headland overlooking the Tywi Estuary near Carmarthen, combines ancient and medieval fortification in a spectacular Welsh coastal setting. The castle's roots trace to an Iron Age promontory fort occupied around 600 BC, later incorporated into a late 12th-century Norman fortification by the Camville family, who held the castle until the early 14th century. The castle's most impressive feature is its massive twin-towered gatehouse, built around 1280, which still commands the landscape. Enclosed by rough stone walls and perched high above the estuary's sandy shores and green farmlands, the castle benefits from one of Wales' most stunning locations. In the care of Cadw, Llansteffan Castle offers visitors layered history spanning centuries and extraordinary views across Carmarthen Bay.
