South Stack Lighthouse, Grade II listed lighthouse in Trearddur, United Kingdom.
The stone lighthouse stands 28 meters high on top of steep cliffs, extending its beam across 45 kilometers of the Irish Sea.
Trinity House constructed South Stack Lighthouse in 1809 to guide vessels along the Dublin-Holyhead-Liverpool maritime route during the growing maritime trade.
The lighthouse forms part of a protected natural area where numerous seabirds, including puffins and peregrine falcons, nest among the coastal cliffs.
Visitors can access the lighthouse by descending 400 stone steps carved into the cliff face, leading to the machine room and exhibition area.
The original whale oil lamps that powered the lighthouse have been replaced with LED technology and Fresnel lenses for enhanced maritime navigation.

Wales features a region with three national parks, including Brecon Beacons and the Pembrokeshire coast park, as well as fortresses like Conwy and Caernarfon castles built by Edward I in the 13th century, and religious buildings such as St. David's Cathedral. The coastline alternates between red sandstone cliffs, sandy beaches, and islands like Anglesey, while the inland reveals mountains, lakes, and valleys such as the Elan Valley with its historic dams. Welsh towns preserve their architectural heritage, with Cardiff as the capital. The Gower Peninsula offers limestone cliffs and sea caves, Tintern Abbey has been a Cistercian monastery since 1131, and Powis Castle features terraced gardens. Former mining regions and botanical sites reflect the country's industrial and cultural evolution.
