Garn Boduan is an Iron Age hillfort and hill near Nefyn, on the Llŷn Peninsula in Wales.
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.[2] The lower stone rampart is the original defence built in the Iron Age.[3] At a later date, perhaps in the 6th/7th century AD, a smaller rampart was built on the eastern side.[3]
