ARBE (Serbo-Croatian RAs), an island in the Adriatic sea, forming the northernmost point of Dalmatia, Yugoslavia. Pop. Arbe is 13m. long; its greatest breadth is 5m. The capital of the same name, is a beautiful walled town on a steep ridge on the west coast. At the seaward end is the 13th century cathedral, behind which the belfries of four churches, at least as ancient, rise in a row along the crest of the ridge ; behind these again are the castle and a background of desolate hills. In another part of the island are excellent state forests. One of the palaces is the birth-place of Marco Antonio de Dominis. Fishing, agriculture, tobacco growing, marble quarry ing, and the ancient silk industry are still maintained. There are excellent springs near the harbour.
