Flag of Pforzheim, Germany Sticker

Pforzheim (German pronunciation: [ˈpfɔʁtshaɪm] ) is a city of over 125,000 inhabitants in the federal state of Baden-Württemberg, in the southwest of Germany. It is known for its jewelry and watch-making industry, and as such has gained the nickname "Goldstadt" ("Golden City"). With an area of 97.8 square kilometres (37.8 sq mi), it is situated about halfway between the cities of Stuttgart and Karlsruhe at the confluence of three rivers (Enz, Nagold and Würm). It marks the frontier between Baden and Württemberg, being located on Baden territory. From 1535 to 1565, it was the home to the Margraves of Baden-Durlach. The City of Pforzheim is a Stadtkreis, meaning it is both a municipality and a district at the same time. Also, it hosts the administrative offices of the Enz district that surrounds the city. During World War II, Pforzheim was bombed by the Allies a number of times. The largest raid, and one of the most devastating area bombardments of World War II, was carried out by the Royal Air Force (RAF) on the evening of 23 February 1945. Nearly one third of the town's population, 17,600 people, were killed in the air raid, and about 83% of the town's buildings were destroyed. The Allies believed that precision instruments were being produced here for use in the German war effort and that the town was a transport centre for the movement of German troops. From 1945 to 1948, Pforzheim (after the initial French occupation) was administered by the United States military and was part of the short-lived state of Württemberg-Baden. In the 20 years following the end of the war, Pforzheim was gradually rebuilt. The town reflects the architecture of the postwar period and has some landmark buildings of the 1950s.
