Building activity occurred in numerous noble palaces and churches during the later decades of the 17th century. Some of the best examples of this architecture are Krasiński Palace (1677-1683), Wilanów Palace (1677-1696) and St. Kazimierz Church (1688-1692). The most impressive examples of rococo architecture are Czapski Palace (1712-1721), Palace of the Four Winds (1730s) and Visitationist Church (façade 1728-1761). The neoclassical architecture in Warsaw can be described by the simplicity of the geometrical forms teamed with a great inspiration from the Roman period. Some of the best examples of the neoclassical style are the Łazienki Palace (rebuilt 1775-1795), Królikarnia (1782-1786), Carmelite Church, Warsaw (façade 1761-1783) and Evangelical Holy Trinity Church, Warsaw (1777-1782). The economic growth during the first years of Congress Poland caused a rapid rise of architecture. The Neoclassical revival affected all aspects of architecture; the most notable examples are the Great Theatre, Warsaw (1825-1833) and buildings located at Plac Bankowy, Warsaw (1825-1828).
