Porec is beautiful small town on the west coast of Istria and today overrun with tourists for six months of the year. It does have an interesting history, though, and this is reflected in the complex of the city's cathedral, named the Euphrasian Basilica for an early bishop. In the early middle ages, the region was part of the Byzantine Empire for about 200 years, and the church's beautiful decoration and especially the mosaics (also visit the adjacent museum!) are evidence of that. There is probably no place outside of Ravenna where early Byzantine art is so well represented, since Istria ceased to be a part of the Empire before the iconoclasts destroyed similar works of art in Constantinople and the eastern Mediterranean. So even if you have come to Porec for the beach and the food, a visit to this great cathedral is definitely required.
