Krk (Italian: Veglia) is the main settlement of the island of Krk, Croatia. It is located on the southwest coast of the island and is the historical seat of the Roman Catholic Diocese of Krk. The city is ancient, being among the oldest in the Adriatic. It has been continuously inhabited since Roman times and was once part of the Byzantine Theme Dalmatia after the Roman Western empire had fallen to the barbarians.
Roman ruins can be seen today in some parts of the town, for example mosaics in the houses. The city had also preserved many medieval fortifications, including Frankopan Castle close to the Kamplin Park, and part of the city walls built during the five centuries when the Republic of Venice ruled the city.
