Laugharne Castle was originally an early 12th century earth and timber ringwork fortress, founded by Robert Courtemain. The stone castle was founded, by the end of the 12th century, when a hall-keep, stood within the earth and timber defences. In the mid 13th century, Guy de Brian added an encasing curtain wall, flanked by two large round towers, to the ringwork. In the late 13th or early 14th century, the simple inner gateway was replaced by an rectangular two storey gatehouse and the outer ward encased, by a curtain wall flanked by a gatehouse. In the 16th century, Sir John Perrot transformed the castle into a Tudor palatial mansion, by raising the curtain wall and gatehouse and adding an impressive range of lodgings around the inner courtyard. Sadly the north side of the castle was destroyed during the Civil War and the remains were then pillaged for building stone. A mile south-west is Roche Castle and 3 miles north is St Clears Castle.
