Pigeon Point灯塔点灯154周年：11月14日庆典近距离看菲涅耳透镜点亮
位于加利福尼亚州圣马特奥县海岸、旧金山以南50英里的Pigeon Point灯塔站州立历史公园，11月14日下午1时至7时举行庆典，纪念这座灯塔的菲涅耳透镜首次点亮154周年。公园入场与停车免费。
庆典活动包括灯塔主题手作与游戏、菲涅耳透镜工作原理讲解、鲸鱼主题讲座、观鸟步行，以及环绕历史灯塔场地的步行导览。访客还可以与当地历史学者JoAnn Semones交流，听她介绍自己最新出版的Pigeon Point历史著作。
留到傍晚的访客，可以在历史悠久的雾号楼里近距离观看菲涅耳透镜点亮。公园说，这是这面透镜明年返回塔身之前，最后一次以这种方式近距离点亮。这面一阶菲涅耳透镜由1,008块棱镜组成，高16英尺、直径6英尺、重2,000磅，于1872年11月15日日落时分首次点亮。
Pigeon Point灯塔高115英尺，是美国最高的灯塔之一，自1872年起为海员引航，如今改用自动LED信标，仍是美国海岸警卫队在用的助航标志。灯塔本体正进行修复，修复工程2024年2月启动，修复完成前灯塔不对外开放，游客可以在场地内观看外观。
公园提示，灯塔场地不许带狗进入，服务犬除外，园内禁烟，也不许放飞无人机。停车场附近设有洗手间与少量野餐桌，历史木匠铺里有公园商店，停车场外100码处有一小片公共海滩。每周日下午2时，公园还提供场地历史步行导览。

Pigeon Point Lighthouse Marks 154 Years: Nov. 14 Celebration Lights the Fresnel Lens Up Close
Pigeon Point Light Station State Historic Park, perched on the central California coast in San Mateo County, 50 miles south of San Francisco, celebrates the 154th lighting of the lighthouse's Fresnel lens on Saturday, November 14, from 1 p.m. to 7 p.m. Admission and parking at the park are free.
The celebration includes lighthouse crafts and games, a look at how the Fresnel lens works, a presentation about whales, a bird walk and a walking tour around the historic lighthouse grounds. Visitors can also talk with local historian JoAnn Semones about her newest book on the history of Pigeon Point.
Visitors who stay late can see the Fresnel lens lit up close inside the historic Fog Signal Building, for the last time before the lens returns to the tower next year. The first-order lens, made of 1,008 prisms, stands 16 feet tall and 6 feet in diameter and weighs 2,000 pounds. It was first lit at sunset on November 15, 1872.
The 115-foot Pigeon Point Lighthouse, one of the tallest lighthouses in America, has guided mariners since 1872. The original lens is no longer in use, and the lighthouse remains an active U.S. Coast Guard aid to navigation with an automated LED beacon. The lighthouse itself is closed while restoration, which began in February 2024, continues, but the tower can be viewed from the grounds.
Dogs are not permitted on the lighthouse grounds, except for service animals, and smoking and drones are not allowed in the park. Restrooms and a few picnic tables sit near the parking lot, a park store operates in the historic carpenter's shop, and a small public beach lies 100 yards from the main parking lot. Guided history walks of the grounds are also offered on Sundays at 2 p.m.
