Schinkel's style was more influenced by Greek than by than Imperial Roman architecture. His most famous buildings are found in and around Berlin. These include Neue Wache (1816–1818), the Schauspielhaus (1819–1821) at the Gendarmenmarkt, which replaced the earlier theater that was destroyed by fire in 1817, and the Altes Museum (old museum, see photo) on Museum Island (1823–1830).
