SOFIA (so-feah), capital of Bulgaria, in an upland plain, about 1,700 ft. above sea-level, between the Western Balkans on the north and Mt. Vita on the south. Pop. 287,976. Two small tributaries of the river Isker, the Perlovetz and the Eleshnitza or Boyana, flow respectively on the east and west sides of the town. Since 1880 the city has been entirely renovated in the "European" style. The oldest building in Sofia is the little round chapel of St. George in the Jewish quarter—originally a Roman bath. Of the principal mosques the large Buyuk Djamia, Tcherna Djamia or Black Mosque, formerly used as a prison, has been transformed into a church; the Banyabashi Djarnia, with its picturesque minaret, is still used by Muslim worshippers. Close to the last-named, in the centre of the town, are the public baths with hot springs (temperature 117° F). The old cathedral of Sveta Nedelya (formerly Sveti Kral), in which the remains of the Serbian king Stefan Urog II. are preserved, was wrecked by an infernal machine on April 16, 1925, but since rebuilt. The church of Saint Sofia (r2th century) contains interesting frescoes. The new cathedral of Alexander Nevski was built as a memorial to the Russians fallen in 1877-78. The palace, occupying the site of the Turkish konak was built by Prince Alexander in 1880-82, and enlarged by King Ferdinand. The city is well drained and has a good water supply; it is lighted by electricity and has an electric tram system. It contains breweries, flour-mills, tan neries, sugar, tobacco, cloth and silk factories, and exports skins, cloth, cocoons, cereals, attar of roses, dried fruit, etc. Sofia forms the centre of a railway system radiating to Constantinople (30o m.), Belgrade (206 m.) and central Europe, Varna, Rust chuk and the Danube, and Kiustendil. The climate is healthy ; owing to the elevated situation it is somewhat cold, and is liable to sudden diurnal and seasonal changes ; the temperature in Jan uary sometimes falls to 4° F below zero and in August rises to I00°. The population, which is mainly Bulgarian, was only 20,501
in 1881. It grew very rapidly after the Balkan and European wars, owing to the influx of refugees.
