Laugharne Castle (Welsh: Castell Talacharn) is a castle in the town of Laugharne in southern Carmarthenshire, Wales. It is located on the estuary of the River Tâf and was originally established in 1116. It was rebuilt as a Norman stronghold in 1215 and has seen many alterations over time, becoming a Tudor fortified manor house in the sixteenth century. It changed hands twice during the English Civil War, being eventually captured by Parliamentary forces in 1644.
