Shut in by hills and forests, and built partly on a promontory overlooking its bay, partly along the shore, Dulcigno is the .prettiest of Montenegrin towns . Its narrow crooked lanes, however, with its bazaars, mosques, minarets and veiled women, give to its picturesqueness a 'decidedly Turkish air . The old quarter, on the promontory, is walled, and has a medieval castle, once of great strength . Turks form the bulk of the inhabitants, although their numbers decreased steadily after r88o, when the population numbered about 8000 . Albanians and Italians are fairly numerous . Dulcigno has a Roman Catholic cathedral and an ancient Latin church . The Austrian Lloyd steamers call at intervals, and some shipbuilding and fishing are carried on; but the harbour lacks shelter and is liable to deposits of silt . To the Romans, who captured it in 167 B.C., Dulcigno was known as Ulcinium or Olcinium; in the middle ages it was a noted haunt of pirates; in the 17th century it was the residence of Sabbatai Zebi (d .

Jew who declared himself to be the Messiah but afterwards embraced Islam . In 1718 Dulcigno was the scene of a great Venetian defeat . It belonged to the Turks until r88o, when its cession, according to the terms of the treaty of Berlin (1878), was enforced by the " Dulcigno demonstration," in which the fleets of Great Britain, France, Germany, Austria and Russia took part .
