Thornton Rath is a prehistoric promontory fort situated inland in Pembrokeshire, Wales. The site is defended by a substantial bank and ditch system that cuts across a natural promontory, a defensive strategy typical of Iron Age fortifications in Wales, though earlier occupation cannot be excluded. The earthwork construction and landscape positioning suggest its primary function was territorial control and settlement protection during the later prehistoric period. The monument remains largely visible as ground earthworks and represents an important example of the defended settlement pattern characteristic of prehistoric Pembrokeshire.
