Linz, capital of Upper Austria, is Austria's third biggest city after Vienna and Graz. It is pleasingly located on both banks of the Danube, which widens here after budding from its slender passageway through the outliers of the Bohemian Forest into the Linz basin. Linz first appears in the records as the Roman fortified campsite of Lentia in the second C. A.D. In 1490 the Emperor Frederick III, who dwelled here from 1485 to 1493, bequeathed the rank of "Hauptstadt". The municipality, now busy with industry and commerce, has widespread port installations. The main part is located on the right bank of the Danube, backed on the west by the Freinberg. On the left bank lies the district of Urfahr, with the Pöstlingberg mounting above it to the northwest.
