query: What was Hans Georg Wenzeslaus von Knobelsdorff's most famous painting?
passage: Georg Wenzeslaus von Knobelsdorff
Knobelsdorff was involved in the construction of St. Hedwig's Cathedral, but it is uncertain to what extent. Frederick II presented the Catholic community with complete building plans, which were probably primarily his ideas which were then realized by Knobelsdorff. The opera house, by contrast, was completely designed by Knobelsdorff and is considered to be one of his most important works. For the frontage of the externally modestly structured building the architect followed the model of two views from Colin Campbell's "Vitruvius Britannicus", one of the most important collections of architectonic engravings, which included works of English Palladian architecture. For the interior he designed a series of three prominent rooms with different functions, which were at different levels, and were decorated differently: the Apollo Hall, the spectator viewing area, and the stage. By technical means they could be turned into one large room for major festivities. Knobelsdorff described the technical features in a Berlin newspaper, proudly commenting that "this theater is one of the longest and widest in the world". In 1843 the building burned down to the foundation. In World War II it suffered several times from bombing. Each time the rebuilding followed Knobelsdorff's intentions, but there were also clear modifications of both the facing and the interior. Soon after they were completed, the opera house and St. Hedwig's Cathedral were featured in textbooks and manuals on architecture.
