Jena is a town in central Germany on the River Saale. With a population of 102,442 (as of 31 December 2004) it is the third biggest town in the federal state of Thuringia.
Jena was first mentioned in 1236 and developed as a market town up until the foundation of the university in 1558.

Today Jena is a manufacturing city, specializing in precision machinery, pharmaceuticals, optics and photographic equipment, and is home to the famous Zeiss optics plant. In 1926 the world's first modern planetarium was built by the Zeiss company in the Damenviertel district of the town. Today the cities economy diversifies into bioinformatics, biotechnology, software and photonics. The metropolitan area of Jena is among Germany's 50 fastest growing regions.
Köstritzer is the maker of the favorite local beer. They make a dark Schwarzbier that is quite popular. A favorite local food is a kind of long sausage, "bratwurst", which is perhaps 30 cm in length and is eaten with brown mustard in a crusty baguette-style bun that is perhaps 8 to 10 cm long, leaving 10 cm or more of sausage hanging from each end, which is quite a sight.
