The Pontifical Basilica di San Nicola is an important church in Bari, located in southern Italy. Its crypt is said to shelter the relics and bones of Saint Nicholas, of Santa Claus fame.
Visitors can explore the basilica's magnificent interior alone or with a guide, and learn how it was built between the 11th and 12th century. It is now an important pilgrimage destination for Roman Catholics and Orthodox Christians from Eastern Europe.
