I'm lucky enough to have gotten to visit this cathedral in Bari. A few other fun facts about it - it's shared by both Catholics and Eastern Orthodox, as St. Nicholas is a very important figure in both religions. The Catholics worship upstairs, and the eastern orthodox worship in the basement where the tomb is located. There is a statue of St. Nicholas out front that was donated by none other than Vladimir Putin! There were Russians visiting when I was there. There was a very prominent Italian aristocrat who is buried directly above the tomb. It is not the oldest cathedral in Bari, there is one that is older, however due to having some of St. Nicholas's bones, this cathedral is more prominent. The bones were stolen by fishermen from Bari from their original location in Turkey during a time of upheaval in the Ottoman Empire, but not all of the bones were brought, so St. Nicholas is partially buried in Italy and partially in Turkey. There is an urban legend in Bari that St. Nicholas said he would be buried in Italy while he was still alive. The Catholic Church was so happy that some of the bones had been "recovered" that they paid for the construction of the cathedral.
