South Stack, Anglesey (Ynys Lawd, Ynys Môn)
Probably the most dramatically sited lighthouse in Wales, this tower on the rocky islet of Ynys Lawd is approached down 400 steps carved into a cliff face and over a bridge flung across a sea-raging chasm. The surrounding buildings have changed over the past two centuries, but the tower remains the same, other than a rebuilding of the lantern in 1874 when a Fresnel lens was installed. South Stack is operated by Trinity House and has tours every day from Easter to October, the only one in Wales open to the public.
