Plassenburg, one of the most important Renaissance buildings in Germany, began. However, George Frederick's successor, Margrave Christian, moved the location of his Residenz in 1604 to neighbouring Bayreuth as the Plassenburg no longer fulfilled the ideas of courtly absolutism, and the expansion of the castle came to an end. Nevertheless, the margravial residence returned to Kulmbach several times, once, in 1605, due to a fire in the city of Bayreuth and then again, for safety, during the Thirty Years War. Kulmbach was also burned as a Protestant town by imperial troops, but the Plassenburg proved impregnable. Finally, in 1642, the residence was moved permanently to Bayreuth, and Kulmbach lost its political importance. As a result, little of significance happened here in the years that followed. When Margrave Charles Frederick Alexander sold the March of Brandenburg-Bayreuth to his cousin, the King of Prussia, on account of his lover, Lady Elizabeth Craven, Kulmbach, too, became Prussian, and the Plassenburg was used in the years that followed as a camp for French prisoners of war. Since the Plassenburg represented an obstacle to French and Bavarian forces advancing against Prussia in 1806, the town of Kulmbach was occupied in October and November that year. After the capitulation of its Prussian garrison, the castle was slighted in order to render it militarily useless. Finally, Kulmbach was granted to Bavaria in 1810. In 1846 it was connected to the King Ludwig South-North Railway. This resulted in a tremendous economic boom - particularly for the breweries - as their products could now be readily exported. So the number of breweries grew to 26 in 1882. In 1890 Kulmbach was elected as a free (kreisunmittelbar) town. In 1933, the NSDAP seized power in Kulmbach and the Imperial School of German Technology (Reichsschule der deutschen Technik) was established in the Plassenburg. As a result, Kulmbach was even given an additional motorway junction which is now the start of today's A 70 autobahn. In early 1945, Kulmbach was captured by American troops without a fight. In the local government reforms of 1972, the districts of Kulmbach and Stadtsteinach were merged and Kulmbach is now the county town.
