Portuguese sailor and explorer Ferdinand Magellan set out 500 years ago to find a route to the riches of the spice islands, north east of present day Indonesia. Through a series of adventures and tragedies, Magellan’s voyage discovered the Straits of Magellan joining the Atlantic and Pacific oceans through Southern America and was the first expedition to completely circumnavigate the World. But Magellan died on the way and the remaining crew were in fact first round the globe. To explore an achievement that changed the World and still influences us today, Bridget Kendall is joined by Dr Rodrigo Cacho, Dr Alison Sandman and Dr Rachel Winchcombe.
