Which is the oldest lighthouse in the world?

The first definite and documented lighthouse in the world was the Pharaohs of Alexandria built in 200 BC, although beacons were certainly used before that. The oldest working lighthouse in the world is at La Coruqa in north-west Spain near the town of Ferol. A lighthouse has been on this site since the time of the Roman emperor Trajan. The world’s first stone lighthouse tower at sea was the Smeaton Eddystone lighthouse built in 1756-9. Smeaton is today known as ‘the father of civil engineering’. When his lighthouse was finished, it was lit with just 24 candles. Today, the power of lighthouse lights could be equivalent to as many as several million candles.
