Bryn Eryr

Bryn Eryr is an Iron Age farmstead near Llansadwrn on Anglesey[1]. Excavations by the Gwynedd Archaeological Trust between 1985 and 1987 uncovered three roundhouses within a low-lying earthwork enclosure[1][3]. Two roundhouses have been reconstructed at the St Fagans National Museum of History in Cardiff, with reconstruction work beginning in 2015 and carried out largely by volunteers[2].
