Kidwelly Castle was originally an early 12th century earth and timber ringwork fortress, founded by Roger de Caen, bishop of Salisbury. In the 13th century, the de Chaworths family founded the stone castle when encasing the ringwork with a curtain wall. Later they made the castle concentric, when adding the square inner ward, flanked on the angles by four large round towers. In the early 14th century, the earls of Lancaster modified the castle, raising the outer curtain wall and flanking it with mural towers and the Great Gatehouse. The four inner towers were heightened and a projecting chapel tower, built overlooking the River Gwendraeth. Visit pending. 9 miles north is Carmarthen Castle.
