Apparently the world’s largest ship graveyard is located in Mauritania. Near the city of Nouadhibou, are hundreds of wrecks in shallow water where they are scavenged or left to decay, and Mauritania has one of the longest trains in the world. The Iron-ore Train is frequently 2.3km long. All we know is that the Parc National du Banc d’Arguin is one of the best birdwatching sites in Africa...
