This is a beautiful interactive map which allows students to investigate the history of the world map.  Designed by Swiss-Italian shipping company MSC Cruises, this is a free-to-use interactive history of the world map.   The map, called In Chartered Waters, begins with the Carthaginians reaching the Atlantic Ocean in 500BC and then travels through the ages exploring how the map developed and the territories that were discovered.  Your journey ends in 1911.  When you come across something like this for free, you faith is restored!
