Two of a kind
Sitting in a field close to the southern end of Llyn Llywenan, the largest natural lake on Anglesey, this pair of Neolithic (New Stone Age) tombs sit just 7ft/21.m apart. Despite their closeness, the tombs’ alignment leaves no space for a shared passage entrance, suggesting that they were built and used at different phases of the Neolithic period. Of the two, the southern tomb is the best preserved, with its large capstone still standing on four uprights.
Our ancient ancestors were not the tomb’s only residents – in the early 1800s a family evicted from their home is said to have used them as shelter.
Last admission 30 minutes before closing
Closed 24, 25, 26 December and 1 January
