Although it is of an insignificant size of 0,14km² it represents a historical interest for the mark that man has left there. The island is completely covered by walls built of stones piled one on top of the other. The ancient wall network is 23.357 km long on an island whose coastal perimeter does not exceed 1431m. These dry stone walls were built only by superimposing simple stones to delimit agricultural plots and protect the olive trees and vines from the wind. Farmers from the neighboring island of Kaprije are said to have started the agricultural colonization of the island in the 19th century, although some of the walls may have been built earlier. These networks of walls is indeed found in some neighboring islands, although the island of Baljenac is the largest concentration of these walls. However, it is estimated that 300 farmers would have built 106km of walls on a surface area of 12 km² in all the neighboring archipelago.
This uninhabited island has a physiognomy totally transformed by man. These agricultural plots give it a physical and totally improvised plot plan, almost random. Seen from the sky the island looks like a maze, a puzzle or a fingerprint, the hundreds of walls giving the island a unique and singular identity.
