Under Old City of Zagreb (Capitol of Croatia) is system of tunnels which were made in past. Till today nobody (and cavers also) knows every channel in this cave system because there is forbidden to come in unstable channels under the old city. At Isle of Pag in Novalja town there is one artificial cave called Talianova Buza. This is ancient Roman water pipe for water supply, long more than 1050 meters. The longest artificial caves in Croatia are in city of Pula. There are plenty of ancient tunnels and also some underground mines for quartz sand. This is system longer than 10 km. Near city of Drnis exist ancient mine of aluminium with depth than 300 meters and lenght several kilometers.
