Sažetak
Eleven caves were explored under the Dubrovnik city Airport in Croatia. This highly weathered area has been in the speleologists’ focus of attention ever since the airport was built in 1961/62. Two vertical caves measuring 31 m and 10.5 m in depth were discovered at that time. These two caves are now situated right underneath the new control tower of the Dubrovnik Airport. A tunnel entrance to the cave that has been known to local population for a long time is situated in the immediate vicinity of the control tower. In late 1950s the entrance to the cave was sealed with concrete because of military airport construction. However, a tunnel was built to enable access to the cave. The cave is about 200 m long and it completely occupies the space underneath the concrete runways of the Dubrovnik Airport. Thanks to the efforts made by speleologists in 2010, the cave was adapted to enable tourist visits, and is now the world’s only tourist cave underneath an operating airport. During the airport extension activities in May 2012, three additional speleological sites were discovered. They were examined along with the other previously discovered caves, from the standpoint of geophysics, geology and speleology. In 2014 and 2015 five new caves were found. The deepest cave is 58 m deep, and the longest one is about 200 m long. Measurements of Radon gas concentration were taken in all this caves. Results were compared with the ones taken in Biokovo tunnel caverns and Vrata tunnel cavern in Croatian part of Dinaric Karst. All of the mentioned caves didn’t have natural entrances on the surface before the first exploration and enginnering work on airport and tunnels were done.
