Karlsruhe is the second-largest city in the state of Baden-Württemberg in southwest Germany near the French-German border. Historically, Karlsruhe owns the Karlsruhe palace which was erected in 1715 by Margrave Charles III William of Baden-Durlach. The two highest courts in Germany (the Federal Constitutional Court and Federal Court of Justice) are located in Karlsruhe, which is therefore also called the city of law. Scientifically, Karlsruhe is characterized by research and education institutions of international reputation (e.g. Karlsruhe Institute of Technology (KIT), Fraunhofer Institute, and in particular also the Karlsruhe School for Optics and Photonics (KASOP) at KIT).
