Because the medieval Kingdom of Croatia was governed by rulers based further south, in areas closer to the Adriatic Sea coast, there are few Early and High Middle Ages monuments preserved in the region—most of them date back to the Late Middle Ages and later periods. There are, however, archaeological sites with features from prehistory and classical antiquity.
Due to the location of medieval Croatian rulers closer to the Adriatic Sea, there are fewer early and high middle age monuments remaining in the area compared to later periods. However, archaeological sites reveal remnants from prehistoric and classical antiquity.
