Replicas of two ships that were part of Christopher Columbus’s 1492 voyage to the New World are in Louisville for a weeklong stay. The Niña and the Pinta, floating museums operated by the Columbus Foundation, based in the British Virgin Islands, have been on a worldwide tour. The Nina has been touring much of the world since 1992, while the Pinta was recently constructed in Brazil. The foundation’s Morgan Sanger says the vessels may appear small by modern standards, but were considered large in the late 15th century. “There weren’t many of them but they were trading vessels that went down the coast of Africa. Then the explorers, Columbus, Magellan and all those guys saw the value of these ships for transatlantic voyages,” he said.
