💡 Pamban Lighthouse

The Pamban Lighthouse is a lighthouse on the Pamban Island in the Indian state of Tamil Nadu. The original tower commissioned in 1846 was 41 ft (12 m) tall and used coconut oil based wick lamps. The current 66 ft (20 m)-high tower was constructed in 1902 into a 66-foot cylindrical tower with a fourth order Fresnel lens. The lighthouse served as a navigational aid for ships transiting the Pamban canal. It was modernized in 2019, and features a solar powered LED-based flash lamp, along with satellite-based communication and response systems.
