Carl Gotthard Langhans (15 December 1732 – 1 October 1808) was a Prussian master builder and royal architect. His churches, palaces, grand houses, interiors, city gates and theatres in Silesia (now Poland), Berlin, Potsdam and elsewhere belong to the earliest examples of Neoclassical architecture in Germany. His best-known work is the Brandenburg Gate in Berlin, national symbol of today’s Germany and German reunification in 1989/90.[1][2]
