of the baroque transformation of the town. In 1850, Mělník became a district town. In 1869, a sugar factory was established, for a long time the only industrial company in the town. In 1874 a railway line was brought to Mělník, which helped to the economic development. In 1888 a bridge over the Elbe was built, and at the end of the 19th century a transhipment depot was built, the basis of the later port.

Viticulture Mělník gives its name to the Mělnická wine region, one of the most northerly in Europe.
