After the 4th century Rijeka was rededicated to St. Vitus, the city's patron saint, as "Terra Fluminis sancti Sancti Viti" or in German "Sankt Veit am Pflaum". From the 5th century onwards, the town was ruled successively by the Ostrogoths, the Byzantines, the Lombards, and the Avars. The city was burned down in 452 by the troops of Attila the Hun as part of their Aquileia campaign. Croats settled the city starting in the 7th century giving it the Croatian name, "Rika svetoga Vida" ("the river of Saint Vitus"). At the time, Rijeka was a feudal stronghold surrounded by a wall. At the center of the city, its highest point, was a fortress.
