Poreč Basilica
With the fragmentation of the Roman Empire Istria ended up under Byzantine rule, opening up the peninsula to the architecture and culture of the Christian East. Poreč Basilica is the best example of what the Byzantines left behind, a largely sixth-century complex with a colonnaded three-aisled interior and an octagonal baptistery on the opposite side of the courtyard. Most famous feature is the dazzling mosaic-covered apse, with portraits of the Virgin and Child standing together with a row of saints and holy men. Golden mosaic tiles are placed at angles to catch sunlight at different times of day, bathing the aisle in heavenly light.
