(Serbo-Croatian Lokrum), a small island in the Adriatic Sea, forming part of the Austrian kingdom of Dalmatia, and lying less than half a mile south of Ragusa. Though barely it m. in length, Lacroma is remarkable for the beauty of its subtropical vegetation. It was a favourite resort of the archduke Maximilian, afterwards emperor of Mexico (1832-1867), who restored the chateau and park; and of the Austrian crown prince Rudolph (1857-1889).1889). It contains an 11th-century Benedictine monastery; and the remains of a church, said by a very doubtful local tradition to have been founded by Richard I. of England (1157-1199), form part of the imperial château.
