Saarbrücken is the capital and largest city of the state of Saarland, Germany. Saarbrücken is Saarland's administrative, commercial and cultural centre and is next to the French border.

The modern city of Saarbrücken was created in 1909 by the merger of three towns, Saarbrücken, St. Johann, and Malstatt-Burbach. It was the industrial and transport centre of the Saar coal basin. Products included iron and steel, sugar, beer, pottery, optical instruments, machinery, and construction materials.

Historic landmarks in the city include the stone bridge across the Saar (1546), the Gothic church of St. Arnual, the 18th-century Saarbrücken Castle, and the old part of the town, the Sankt Johanner Markt (Market of St. Johann).

In the 20th century, SaarbrÜcken was twice separated from Germany: from 1920-1935 as capital of the Territory of the Saar Basin and from 1947-1956 as capital of the Saar Protectorate.

In modern German, Saarbrücken literally translates to Saar bridges (Brücken is the plural of Brücke), and indeed there are about a dozen bridges across the Saar river. However, the name actually predates the oldest bridge in the historic centre of Saarbrücken, the Alte Brücke, by at least 500 years.

The name Saar stems from the Celtic word sara (streaming water), and the Roman name of the river, saravus.

There are two theories about the origin of the second part of the name Saarbrücken. The most popular theory states that the historical name of the town, Sarabrucca, derived from the Celtic word briga (hill, or rock, big stone), which became Brocken (which means rock or boulder) in High German. The castle of Sarabrucca was located on a large rock by the name of Saarbrocken overlooking the river Saar. A minority opinion holds that the historical name of the town, Sarabrucca, derived from the Old High German word Brucca (in German), meaning bridge, or more precisely a corduroy road, which was also used in fords. Next to the castle, there was a ford allowing land-traffic to cross the Saar.
