 These include a 1535 altar polyptych by Girolamo da Santacroce in the Franciscan monastery on Košljun island, while a Paolo Veneziano polyptych from Benedictine abbey in Jurandvor near Baška is in the collection of the Roman Catholic Diocese of Krk.The economy of the Croatian Littoral is largely centered on the city of Rijeka, whose economic impact is felt directly not only in the geographic region, but also in other parts of Primorje-Gorski Kotar County—Gorski Kotar and Liburnia (modern region)—and a substantial part of Lika-Senj County.The most significant economic activities in the Primorje-Gorski Kotar County are transport, largely based on activities of the Port of Rijeka, shipbuilding and tourism in the coastal areas representing a part of the Northern Croatian Littoral, and forestry and wood processing in the Gorski Kotar region in the hinterland.
