Comprehensive maps for the routes of Prince Henry the Navigator are not available online. Websites such as Timetoast.com and Mrnussbaum.com offer summary maps of Henry's expeditions. However, these are incomplete. They consolidate Henry's voyages into a single line without identifying the routes or destinations of his explorers.
Prince Henry of Portugal sponsored a series of 15th-century voyages in search of a water route to Asia, explains The Mariners' Museum. Expeditions Henry backed include those in 1414, 1418, 1423 and 1436 as well as several thereafter. Portuguese sailors reached as far south as Sierra Leone prior to Henry's death in 1460. In 1488, 28 years after Henry's death, Vasco de Gama discovered a passage below Africa.
