Built by the British in 1857 it is one of the largest in Greece. It is 25 m high and is located at Cape Spathi, at the northern tip of the island. You will need to walk a great distance should you wish to visit it. For more information talk to the people in Karavas. There is also a lighthouse keeper who might let you in. In the past, and in addition to the flashing light, flags were used as signals during the daytime for boats, kept in a building near the lighthouse. The place is stunningly beautiful. Weather permitting you can see the entire Gulf of Laconia, from Cape Maleas to Cape Tenaro.
