There are approximately 1200 islands in the
Adriatic Sea, 69 of which are inhabited. A recent study by the Institute of Oceanography from
Split (2000) shows that there are 1246 islands: 79 large islands, 525 islets and 642 ridges and rocks. Italian
Scuola di Geografia of
Genova states that the number is greater if added the small islands in the Italian lagoons of Venice and Grado and the so-called "islands of the Po delta".
