The sacral architecture was now dominated by the Protestant church. After 1763 the small modest churches of the past were gradually abandoned and large monumental churches were built. Groundbreaking for the development of these churches were the churches in Cosel by Joh.M. Pohlmann and K.G. Langhans and in Polnisch Wartenberg (Syców) by K.G. Langhans in 1785. The new standards of these neo-classical churches were soon adopted by the churches in Waldenburg (Wałbrzych), Reichenbach (Dzierżoniów) and Münsterberg (Ziębice). The building activities of the Catholic Church stagnated until the mid 19th century. The residential architecture between 1740 and 1806 was marked by dynamic changes regarding styles and types. New town palaces however were rarely built. The most important one was Palais Hatzfeldt in Breslau, one of the first neo-classical buildings in Europe, designed in 1764 by I. Ganevale and K.G. Langhans. Other palaces adopted the new style after 1770. The public initiatives affected mainly military buildings: monumental fortifications in Silberberg (Fort Srebrna Góra), Neiße and Glatz (Kłodzko Fortress) as well as new barracks in Breslau and Brieg. According to the welfare policy of Frederick II of Prussia new hospitals and workhouses were erected (Kreuzburg, Breslau), and with the beginning industrialization of Upper Silesia entire residential developments were planned. New administration structures were adopted after the Prussian ministry for Silesia was closed in 1808 and the reforms by Heinrich Friedrich Karl vom und zum Stein and Karl August von Hardenberg were implemented. From now on every building project had to be accepted by the building inspection department, which itself was under the control of the royal police headquarters. Every town appointed its municipal architect and local building deputation controlled the technical aspects of every project. These principles were in effect until 1900. After 1820 positive results of these reforms became visible as a new period of building activity began. Most of these activities were now carried out in the cities, which became dominant in the shaping of Silesia's architectural landscape. Dozens of theaters, houses for different associations, schools, hospitals or asylums were built. The most important artistical center was Breslau, and the most important Silesian architect until 1840 was Carl Ferdinand Langhans, son of Carl Gotthard and creator of the exchange, the theater, the loge "Friedrich zum goldenen Zepter" in Breslau and the theater in Liegnitz. A new type of apartment buildings began to evolve and the rich bourgeoisie began to live in
