While the Pre-Romanesque was a period of many small churches, the Romanesque was the age of imposing cathedrals. Many can be found along the Croatian coast and nearby lands: in Istria, Dalmatia, and Primorje. Cities such as Poreč, Rab, Zadar, Trogir and Split were built along the Dalmatian coast with stone houses and large imposing churches with three naves, three apses, columns, arches, arcades and a wooden roof. Cathedrals were built in Senj, Krk, Rab, Zadar, Trogir, Dubrovnik and Zagreb (where a bishopric was founded in 1094).
