Stuttgart  is the capital of Baden-Württemberg, Germany, with a population of approximately 606,000 in the immediate city and more than 2,6 million people in the metropolitan area.
Stuttgart was founded in the 10th century; its name is a modern version of the original Stutengarten ("mare's garden"). Presently it is the 6th largest city in Germany. It is most famous for its automotive industry - both Porsche and Mercedes-Benz have their headquarters in Stuttgart and both have car museums.
Stuttgarters are amazingly friendly people who will forgive you if German isn't your first or second (or any) language. If you do speak German well: beware that many people speak the local Schwäbisch dialect natively which may somewhat effect their standard German - which however everyone can speak. They love to practice other languages (especially English) and will try to help you. Stuttgart is a big city with a small-town atmosphere.
