Of all the Croatian islands, Vis is the most mysterious – even to locals. The furthest of the main Central Dalmatian islands from the coast, Vis spent much of its recent history serving as a military base for the Yugoslav army, cut off from foreign visitors from the 1950s right up until 1989. The isolation preserved the island from development and drove much of the population to move elsewhere in search of work, leaving it underpopulated for many years.
