南斯塔克灯塔，霍利希德，威尔士，英国

南斯塔克灯塔建在威尔士圣岛崎岖的悬崖上，俯瞰着爱尔兰海的深水区。自1809年建成以来，这座91英尺高的白塔一直为水手们指引方向；它为都柏林-霍利黑德-利物浦航线上的船只提供了安全通道。灯塔建成时，使用抹香鲸油点亮灯具；但多年来，灯塔的机械装置已升级为更先进的技术，如LED灯泡和菲涅尔透镜。灯塔于1984年实现自动化，其强大的光束照射范围可达28英里，至今仍是重要的导航设备。当夕阳西下，天空布满五彩斑斓的色彩时，南斯塔克灯塔在黄昏中的剪影令人叹为观止。游客们会勇敢地从陡峭的悬崖上爬下400级台阶，探索灯塔以及它的机房和展览区。

South Stack Lighthouse, Holy Island, Wales

Built on the rugged cliffs of Holy Island, Wales, the South Stack Lighthouse stands watch over the deep waters of the Irish Sea. The 91-foot-tall white tower has guided sailors since its completion in 1809; it provides safe passage for ships on the Dublin-Holyhead-Liverpool route. When it was built, sperm whale oil was used to light the lamps; however, over the years, the mechanism has been upgraded to more advanced technology like LED bulbs and Fresnel lenses. Automated in 1984, the lighthouse continues to serve as a vital navigational aid, with its powerful beam shining up to 28 miles. As the sun sets and the sky fills with colors, the silhouette of the South Stack Lighthouse in the dusk makes for a stunning sight. Visitors brave the 400-step descent down the steep cliff face to explore the lighthouse, including its engine room and exhibition area.
