Warsaw
Gothic architecture is represented in the majestic churches but also at the burgher houses and fortifications. The most significant buildings are St. John's Cathedral (14th century), a typical example of the so-called Masovian Gothic style; St. Mary's Church (1411), a town house of Burbach family (14th century); Gunpowder Tower (after 1379); and the Royal Castle "Curia Maior" (1407–1410). The most notable examples of Renaissance architecture in the city are the house of the Baryczko merchant family (1562), a building called "The Negro" (early 17th century), and Salwator tenement (1632). The most interesting examples of Mannerist architecture are the Royal Castle (1596–1619) and the Jesuit Church (1609–1626) at Old Town. Among the first structures of the early Baroque, the most important are St. Hyacinth's Church (1603–1639) and Sigismund's Column (1644).
Collegiate Gothic
At the University of Pittsburgh, Charles Klauder was presented with a limited site and opted for verticality. The Cathedral of Learning (1926–37), a steel-frame, limestone-clad, 42-story skyscraper, is the world's second tallest university building and second tallest Gothic-styled building. It has been described as the literal culmination of late Gothic Revival architecture. The tower contain a half-acre Gothic hall whose mass is supported only by its 52-foot (16 m) tall arches. It is accompanied by the campus's other Gothic Revival structures by Klauder, including the Stephen Foster Memorial (1935–1937) and the French Gothic Heinz Memorial Chapel (1933–1938).
