The Royal Opera, the Tiergarten, Sanssouci Castle.... Oh, please forgive me. I was just checking my construction plans. My name is Georg Wenzeslaus von Knobelsdorff, I am the architect of Frederick the Great. He has entrusted me with numerous assignments: I will create a new look for Berlin and Potsdam. The King and I are old friends: we share the same enthusiasm for arts and architecture. When he was still Crown Prince, he paid for my grand tour through Italy, France and Flanders. Impressions from my journey inspire my buildings. Admittedly, finances are not my strong suit. But who could have guessed that the ground for the Opera was marshy? Now the King demands detailed reports. Maybe he doesn't trust me anymore? He once called me “lazy like an artillery horse". Knobelsdorff died in 1753. After his death Frederick the Great praised his architect friend in a eulogy. Today you can still see Knobelsdorff's design at the Opera or "Unter den Linden".
