It is an underground complex of water reservoirs, built in the 15th century for city's water supply. Now it's a multimedia exhibition center Bunari - Tajne Šibenika ("Bunari - Secrets of Sibenik"). The reservoirs are now dry and decorated as a museum/gallery and a cafe. It has 7 sections: (Šibenik's treasure, food and drink, shipwrecks around Šibenik, persons from the past etc.). Concerts, stand-up comedy shows etc. often take place at the cafe. Very interesting spot.
