Brynsiencyn Round Barrow

A round barrow stands on the Isle of Anglesey near the village of Brynsiencyn. Built by Neolithic or Bronze Age people for ceremonies or burials, it sits west of a local hill called the Garn. The mound measures 24 metres across and rises just under two metres high. Cadw, Wales’ historic environment service, keeps the site on its list with the reference AN060. Almost four hundred such barrows appear in the register, more than any other ancient monument type. These barrows first appeared around 3000 BC and continued until the end of the Bronze Age, roughly 600 BC. Most were raised between 2400 and 1500 BC, showing how long this tradition lasted. The eastern barrow at Brynsiencyn is one of many chambered tombs found across Wales. Similar sites include passage graves and long cairns built for communal burials. Visitors reach the low grassy mound through farmland and quiet lanes. The flat top offers a wide view over the surrounding countryside. A low stone kerb once marked the edge, though much has been worn away. The site sits in open ground, free of modern buildings, so the ancient shape stands clear. A short walk from the lane brings the barrow into sight, unchanged after thousands of years.
