Castell Moeddyn Fach

Castell Moeddyn Fach stands on a low hill near Llanarth in Ceredigion. It is one of about 570 Iron Age hillforts scattered across Wales, though only around 300 appear on Cadw’s official list. Cadw has given it the unique SAM code CD083 to mark its protected status. Most hillforts were built on high ground to give defenders a military advantage over attackers. Their purpose was to shelter homes and military camps before the Romans arrived. The fort belongs to the golden age of British hillforts, which lasted from 200 BC until AD 43. Many forts were reused and strengthened by the Romans, including Dinorben in north Wales. Tre’r Ceiri is often cited as one of the most impressive hillforts in Wales, yet it is smaller than Llanymynech, the largest in north-west Europe by area. Llanymynech covers about 57 hectares, while Castell Moeddyn Fach is much more modest in size. Visitors reach the site by following a quiet farm track to the hilltop. The remains consist of low grassy banks that once formed the defensive ramparts. From the summit there are wide views over rolling Ceredigion countryside. The peaceful setting shows why the hill was chosen long ago. A short walk around the perimeter lets you trace the outline of the old walls.
