The island of Murter encompasses 17.9 km2 (with nearby islands 25.6 km2.) The island was first mentioned by
Scardon in memorials of
Ptolemy. It was probably first named Srimač in 1251. When
King Bela arrived in
Dalmatia and in Klobučac near
Trogir, he issued a
deed of donation which details the borders of Šibenik. The island of Srimač was mentioned as a part of Šibenik. The
Croatian name Srimač was used until 1740, but since 1443, the name Murter is also mentioned (Insula mortari, from the words
Mor, sea and
tar, tower). In Roman times, there had been a town called Collentum on the island in the area of today's Gradina, which was also mentioned by Ptolemy. A significant colonisation did not occur before the first half of the 16th century, during the
Turkish incursion in
Ravni Kotari and the Šibenik coast, and
Venetian-Turkish conflicts during the second half of the 16th and the first half of the 17th century. Older villages are Murter and Betina, younger ones are Tisno and Jezera. Betina was mentioned for the first time in 1423. at which time the population was 15 persons in 8 houses, which points to an earlier origin of the village. In 1597, there were 16 houses in Betina, and in 1678, 350 persons lived there, belonging to 52 families. Since the middle of the 16th century, Betina has been inhabited by refugees from
Vrana, especially since 1573, when Vrana fell under Turkish occupation. The church was built in the 16th Century. On the nearby island of
Sustipanac, there was a monastery of the
Franciscan friars. == Population ==
