Llawhaden Castle (Welsh: Castell Llanhuadain) (grid reference SN 073175) is a ruined castle in Llawhaden, Pembrokeshire, Wales, 10 miles (16 km) east of Haverfordwest.[1] A motte-and-bailey castle is thought to have previously occupied the site and the present structure was built by the bishops of the Diocese of St David in the 13th century. The castle was abandoned in the 16th century and some of the stone was removed for local building projects. The site is privately owned by the Lord of the Manor of Llawhaden and managed by Cadw.
