Tŵr Bach, Llanddwyn
One of two navigation towers on this picturesque tidal island, it was originally a simple unlit daymark guiding mariners into the southern entrance of the Menai Strait. It was later supplemented by the nearby Tŵr Mawr, a larger tower with a light. When that light was removed in 1975 an electric beacon was added to the top of this tower, which is still active.
