Mynydd Bach round cairn

A small Bronze Age round cairn stands on the low, open moorland of Mynydd Bach near Aberffraw on the Isle of Anglesey. Built about 4,000 years ago, it is one of nearly 400 burial mounds recorded by Cadw, more than any other kind of ancient site in Wales. Excavations in 1952–53 uncovered burnt pottery and cremated human bone inside the low stone heap. The mound measures eight metres across but only half a metre high, a modest shape that reflects its early date between 2400 and 1500 BC. Its builders belonged to communities who raised such cairns first around 3000 BC and continued the tradition until the end of the Bronze Age about 600 BC. Cadw lists the site as AN149, keeping its record alongside other chambered tombs and burial chambers across Wales. Visitors find a quiet grassy rise with a low ring of stones marking the centre. The wide horizon shows Anglesey’s flat coastal plain and distant hills. No fences or paths disturb the open ground, so the cairn sits exactly as it did when first raised.
