Euphrasian Basilica and the Cathedral of the Assumption is a Roman Catholic basilica in the Istrian town Porec, Croatia. The episcopal complex, which involves the basilica itself, a sacristy, a baptistery and the chime tower of the close by diocese supervisor's castle, is an astounding case of early Byzantine design in the Mediterranean locale. The Euphrasian basilica has generally held its unique shape, however mishaps, flames and tremors have modified a couple of subtleties. Since it is the third church to be based on a similar site, it hides past structures, for instance the incredible floor mosaic of the past basilica from the fifth century. Given the remarkable worth, it is enlisted in the UNESCO World Heritage List since 1997. The basilica is the church of the Catholic Diocese of Porec-Pula.
