The Basilica di San Nicola in Bari Italy. The tomb of Saint Nicholas is in the lower level of the basilica. Saint Nicholas gave everything he could to the poor. His reputation and stories grew. The Dutch celebrated him every year on December 6th, the day of his death. They brought the tradition with them to New Amsterdam (New York). The Dutch name for Saint Nicholas translated to Santa Claus. Over the years the story and the traditions morphed into the Santa Claus that we know and love today.
