照亮前行之路 Where is this lighthouse?

国际灯塔灯船周末

今天照片中的灯塔位于葡萄牙南部海岸阿尔加维的卡沃埃罗。阿尔凡齐纳灯塔建于1919年，照耀着大海，帮助船只在该地区周围危险的水域航行。这座灯塔是著名的旅游胜地，同时也是该地区与海洋紧密联系的象征。如果你有幸住在灯塔附近，那么本周末就是拜访灯塔的最佳时机。

今天是国际灯塔灯船周末的第一天，这次活动是为了庆祝这一重要的海上基础设施。自从人类在海上航行以来，灯塔就一直在保护水手的安全。最初，灯塔由火和油灯供电，需要灯塔看守人来维护它们。然而，如今大多数灯塔都已实现自动化，并安装了电光源。在太深或不适合建造灯塔的水域，人们通常会使用灯船。

International Lighthouse and Lightship Weekend

The lighthouse featured in today's image stands in southern Portugal's popular Algarve region. Built in 1919, Alfanzina Lighthouse helps ships navigate dangerous waters near the town of Carvoeiro. A popular tourist destination, the lighthouse also has become a symbol of the region's deep links to the sea. If you're lucky enough to live near a lighthouse, this weekend is the perfect time to pay it a visit.

Today marks the start of International Lighthouse and Lightship Weekend, celebrating this vital maritime infrastructure. Originally, lighthouses were powered by fires and oil lamps, requiring lighthouse keepers to maintain them. These days, however, most lighthouses have been automated and installed with electric light sources. In waters that are too deep or otherwise unsuitable to build a lighthouse, lightships—moored vessels outfitted with beacon lights—have often been used.
