This basilica seems to me one of those buildings that are much more prettier in the inside than on the outside

The Euphrasian Basilica (Croatian: Eufrazijeva bazilika, Italian: Basilica Eufrasiana) or the Cathedral Basilica of the Assumption of Mary is a basilica in Poreč, Croatia. The episcopal complex, including, apart the basilica itself, a sacristy, a baptistery and the bell tower of the nearby archbishop's palace, is an excellent example of early Byzantine architecture in the Mediterranean region.
The Euphrasian basilica has for the most part retained its original shape, but accidents, fires and earthquakes have altered a few details. Since it is the third church to be built on the same site, it conceals previous buildings, for example the great floor mosaic of the previous basilica from the 5th century. - in: wikipedia
