The Cathedral of St. James in Šibenik is a triple-nave Catholic basilica and the most important architectural monument of the Renaissance in Croatia. Since 2000, the cathedral has been on the UNESCO World Heritage List. It is dedicated to Saint James the Greater, and is also known as “St. Jacob’s”, because Croats use the same name both for “James” and “Jacob”. Šibenik Cathedral is the only cathedral in all of Europe built exclusively of stone and the first prefabricated building in Europe built on the principle of grooved slabs.
