Castell Mawr Hillfort

Castell Mawr is an Iron Age hillfort in Pembrokeshire, Wales. It stands near the village of Eglwyswrw on a low rise. The fort is one of several called Castell Mawr in Wales. Experts believe it dates from the Iron Age, around 800 BC to AD 43. Its circular shape suggests it was built for family defence. Similar small forts appear across Wales and eastern Ireland, showing links between the regions in Celtic times. The site offers a rare glimpse of a family-run stronghold from pre-Roman Britain. Such hillforts usually occupied hilltops for military advantage. Castell Mawr’s modest size shows it was not a major tribal centre. Many forts were reused or rebuilt after the Roman invasion, though Castell Mawr’s later use is not recorded. Iron Age hillforts flourished in Britain between 200 BC and AD 43, before Rome took control. Visitors reach the fort by a short walk from nearby lanes. The grassy bank and ditch still mark the circular enclosure. From the top there are wide views over rolling Pembrokeshire countryside. The site is quiet, with few visitors, and feels much as it did two thousand years ago. The low profile and simple form let the landscape speak for itself.
