Garn Boduan

Garn Boduan is an Iron Age hillfort and hill near Nefyn, on the Llŷn Peninsula in Wales [1]. In a survey in the 1950s the traces of over 170 round houses were identified on this site, and around 100 round houses are still visible on the ground [1]. Between 100 and 400 people may have lived in this fort [1]. The lower stone rampart is the original defence built in the Iron Age [1]. At a later date, perhaps in the 6th/7th century AD, a smaller rampart was built on the eastern side [1].
