Y Werthyr Hillfort is a prehistoric defensive enclosure located on the island of Anglesey in Wales. The site comprises a substantial earthwork featuring a single rampart with an external ditch, characteristic of Iron Age hillforts in Wales, and is likely to date from the later prehistoric period. Its strategic position would have commanded views across the surrounding landscape, suggesting a role in territorial control and settlement defence during the Iron Age. The monument remains an important example of prehistoric fortification practices in North Wales and is protected as a scheduled ancient monument under the Welsh heritage designation system.
