Castell Moel is possibly a 16th but probably 17th century fortified manor house, founded by the Rede family. Standing on a plateau which overlooks the River Tywi, are the overgrown remains of a late medieval L-plan hall house. The main eastern block is a first floor hall and set in the re-entrant angle, is an adjoining high stair turret. The western block is a two storey wing, with a porch and a cellar and the walls of the castle, once supported a crenellated parapet. 3 miles north is Carmarthen Castle and 5 miles south-west is Llansteffan Castle.
