Gontos, a royal free city of Hungary, capital of a cognominal county, is situated on a point of land formed by the junction of the Waag with the Danube, and constituting the eastern extremity of the island of Schutt. The fortress of Komorn, founded by Mathias Corvinus in the fifteenth century, has been rebuilt and strengthened since 1803, and is now one of the strongest in Europe. It has never been taken; and in 1848-9 it successfully resisted all the efforts of the Austrian army. The town itself is irregularly built, and the streets are narrow and dark. It has four Roman Catholic churches, one Greek, one Lutheran, and one Reformed church, a Jewish synagogue, a Roman Catholic and a Protestant gymnasium, and two theatres. Komorn is a steam-packet station, and carries on an extensive trade in grain, wine, timber, and fish. Pop. (1851) 19,113.
