Сан-Витале
The mid-6th century Bishop of Poreč ( or ; ) replaced an earlier 4th century basilica with the magnificent Euphrasian Basilica in the style of contemporary basilicas at Ravenna. Some column capitals were of marble from Greece identical to those in Basilica of San Vitale and must have been imported from the Byzantine centre along with the columns and some of the "opus sectile". There are conch mosaics in the basilica's three apses and the fine "opus sectile" on the central apse wall is "exceptionally well preserved".
