Twr Mawr Lighthouse is situated on the stunning and tranquil Ynys Llanddwyn (Llanddwyn Island). It is situated at the far end of the Island, marking the western approach to the Menai Strait. The Lighthouse tower on Llanddwyn Island is so similar to many of the windmill designs on Anglesey, it is thought that it may have been a windmill at one time.
