Bryn Eryr is an archaeological site near Llansadwrn, Anglesey, Wales, where the remains of an Iron Age farmstead, consisting of three roundhouses, have been excavated. [1] Excavations took place in the period between 1985 and 1987, and were carried out by the Gwynedd Archaeological Trust. [2]
Two of the roundhouses have been reconstructed at the St Fagans National Museum of History in Cardiff. [3] Reconstruction of the buildings began in 2015 and was carried out mainly by volunteers, including schoolchildren. It was part of a development financed by a £11.5 million grant from the UK's Heritage Lottery Fund. [4] It was opened to the public in 2016. [5]
