Ústí nad Labem (German Aussig an der Elbe) is a statutory town in
northwestern Bohemia, the center of the Ústí Region. It lies at the
confluence of the Elbe and Bílina rivers between the Bohemian
Central Mountains and the Ore Mountains. Approximately 93,000
inhabitants live here and it is part of the half-million North
Bohemian agglomeration. Ústí nad Labem is a university town with an
industrial tradition and sports facilities, an important railway and
road junction, but it does not have many preserved historical
monuments. Ústí nad Labem is 90 kilometers from Prague, 180
kilometers from Pilsen, 130 kilometers from Karlovy Vary, 95
kilometers from Liberec and 65 kilometers from Dresden, Germany.
The name was probably, due to its location at the confluence of two rivers, derived from the Old Czech word ustie (estuary). The name Aussig an der Elbe has been used in German since at least the 15th century. The city was mostly German-speaking for most of its existence.
The name Vsk super Albium is documented in Latin records from 1368 (in the records of the Prague Benedictines at St. George's). The title Austia super Albea was used in the title of the Municipal Judicial and Commemorative Book, founded in 1438 as part of the city's renewal 12 years after the Hussite conquest and kept until 1514. The memorial book was written first in Latin, from 1440 some entries also in German and in 1474 a Czech appeared, which prevailed around 1490. In the title of the book of wills kept in the years 1504–1585, the city is called Ausigh super Albea, the entries also alternate in three languages, initially Czech predominates.
