The first and oldest written document on a cave in Croatia is a church paper handwritten in latin language in 1096. that describes the boundaries of the estate of Ugljan island owned by the monastery of Saint Chrysogonus from Zadar.
This "place" is really a cave located north of Željina bay. It is 28 meters long, on the west side of Ugljan island at about 100 meters of altitude. The cave was explored and described in 1952. by the academician Mirko Malez.
The document drom 1096 proves that more than 900 years ago the people were well-aware of our caves and that on the Ugljan island they were used as landmarks that mark the boundaries of estates.
