With the End of the 18th century, the epoch of classicism also began in Berlin and Brandenburg.
Berlin's important architects of early classicism were Gotthard Langhans (Gate of Brandenburg), Friedrich Wilhelm von Erdmannsdorff, and David Gilly, later the founder of the architectural academy.
At the beginning of the 19th century Karl Friedrich Schinkel began his work. He not only brought Prussian-style classicism to its peak, but also founded Romanticism.
The Alte (old) Museum, the Neue Wache (New Guardhouse) and the Schauspielhaus (theater) belong to Schinkel's work.
Also at the beginning of the 19th century, Peter Josef Lenné, probably the most distinguished landscape architect, planned the reconstruction of the Tiergarten (Berlin's central park) and the Landwehrkanal (canal) in Berlin, and designed an immense Roman landscape around Potsdam.
In this unique countryside, which recently was put on UNESCO's World Heritage List, antique-looking villas, early Christian churches and cloisters, and classical ruins were built.
This classicist period can probably be described as the peak of Prussian architecture. After Schinkel's death, his students Friedrich August Stüler (Old National Gallery, New Museum, St. Matthäi-Church) and Ludwig Persius maintained his tradition.
