in the late 18th century, the main proponent of Classicism in the Golden age was Christian Frederik Hansen who developed a rather severe style with clean, simple forms and large, unbroken surfaces inspired by the architecture of ancient Greece and Rome. From 1800, he was in charge of all major building projects in Copenhagen where he designed the Copenhagen City Hall & Courthouse (1805–1815) on Nytorv. He was also responsible for rebuilding the Church of Our Lady ("Vor Frue Kirke") and designing the surrounding square (1811–1829).
