the town of Krk played a major role in spreading of Croatian education and culture in the area. 20th century The Italian Occupation (1918–1920) was brief, and Krk was handed over to Croatia, then in Yugoslavia, by the Treaty of Rapallo, Italy took Krk again in the Second World War (1941–1943), and German occupation followed from 1943 to 1945. The post-war development of Krk was led by tourism. The building of an airport and then a bridge over to the mainland ensures the future of the development of tourism on this island. In Omišalj there has also been industrial development. The bridge is at the north end of Krk island and uses the small island of Otoćić Sveti Marko (St. Mark's Islet) as a mid-support. Economics and infrastructure Krk is located rather near the mainland and has been connected to it via a two-arch concrete bridge since 1980, one of the longest concrete bridges in the world. Due to the proximity to the city of Rijeka, Omišalj also hosts the Rijeka International Airport as well as an oil terminal representing a part of the Port of Rijeka and a petrochemical plant. Since January 2021,there is an active Krk LNG terminal storage and regasification ship moored in Omisalj, north of Krk, able to receive large LNG carrier ships and then to pump the gas into trans-European pipelines. Krk is a popular tourist destination, due to its proximity to Slovenia, southern Germany, Austria, and northern Italy. Since the collapse of the Eastern Bloc, many tourists have appeared from Slovakia, Hungary, Romania, and other former Eastern Bloc countries. Fiber access network In 2009 the municipality started the project of building a fiber-optic network on the whole area of the city (the town of Krk and 14 neighboring villages) as part of the town infrastructure. Thereby the focus is on building the passive part of the network, which is the most expensive one and the prerequisite for service providers being able to provide ultra-fast Internet connections and new e-Services. The project is covering 6,243 inhabitants and 6,000 households. The first issue was the elaboration of a cost-benefit analysis in 2009/2010 followed by a preliminary network planning. At the beginning of 2013 the building authority issued the relevant approval. The next step is the elaboration of the main project which is the condition for getting the building permission and by which the project can apply
