Baljenac (or Bavljenac) is a small island in the Adriatic Sea located just off the coast of Croatia on the Sibenik archipelago. It is an islet of about half a square mile entirely and is covered by a series of dry-stone walls which when seen from above looks like a gigantic human fingerprint, thanks to its oval shape and long rows of stones similar to papillary lines. People often wonder who “created” the fingerprint island. Is it man-made? Is it a natural wonder? The answer is: both! The look of the island comes from the structure of the stone dry walls on the island, called suhozid in Croatian. The length of the dry stone walls is simply staggering — there are more than 23 kilometres of stone dry wall on this tiny area of only 0.14km2 .
