Asinara
A former prison island, closed to the public for a century, whose isolation left it almost undeveloped.
Updated 16 October 2026

AI illustration
Asinara held a quarantine station from 1885 and then a prison, which meant the island was closed to outsiders for more than a century; the effect was that fifty-two square kilometres of coast were never built on. The prison closed in 1998 and the island became a national park. Its emblem is a population of small white albino donkeys, found only here, alongside mouflon and wild boar. Prison buildings remain across the island in various states. Access is regulated: private boats and cars are not allowed, and visits are by organised boat with jeep, bicycle or guided walking on set routes.
Background
From end to end the island runs 17.4 kilometres. At its narrowest, at Cala di Sgombro, it is 290 metres across, widening to 6.4 kilometres in the north. Four mountainous blocks are linked by a low, narrow strip along the coast. Steep rocky shores face west, while the east is broad and level, rising no higher than 50 metres, and holds all three sandy beaches. Punta della Scomunica is the summit at 408 metres. Over 80 percent of the island is metamorphic rock, including black Hercynean amphibolites 950 million years in age, which are the oldest rocks in Italy. In 1885 it passed to the state, and about 100 farming and fishing families moved to Sardinia and founded Stintino.
