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