The English Channel. The highway of the sea with over 400 cargo ships that sail through daily. Beachy Head lighthouse warns sailors of the "Sailors' Graveyard" - the most dangerous waters along England's south coast. Here are rocks, rough seas and dark storms. In the 18th century, a priest provides light along the coast, and later as many as three lighthouses are built at Beachy Head. But how do the engineers manage to build the lighthouses in the harsh conditions?
