9th August 2010 year we went with my girlfriend to Braunschweig.
Up to the 12th century Braunschweig was ruled by the Saxon noble family of the Brunonen, then, through marriage, it fell to the House of Welf. In 1142 Henry the Lion of the House of Welf became Duke of Saxony and made Braunschweig the capital of his state (which, from 1156 on, also included the Duchy of Bavaria). He turned Dankwarderode Castle, the residence of the counts of Braunschweig, into his own Pfalz and developed the city further to represent his authority. Under Henry’s rule the Cathedral of St. Blasius was built and he also had the statue of a lion, his heraldic animal, erected in front of the castle. The lion subsequently became the city’s landmark.
Henry the Lion became so powerful that he dared to refuse military aid to the emperor Frederick I Barbarossa, which led to his condemnation and fall. However, his son Otto (IV), who could regain influence and was eventually crowned Holy Roman Emperor, continued to foster the city’s development. (wikipedia)
I have to say that the city was not too much interested. The day was cold.
