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).
Gothic secular and domestic architecture
It was not only new, founded cities that had extensive building regulations. London, Florence, Paris, Venice and numerous smaller cities in Spain and Italy had rules concerning not only the height and shape of buildings, but also for example regulating the width of streets, the projection of roofs and rules concerning waste management, drainage and fire regulations. The Piazza del Campo in Siena, Italy is one of the earliest examples of "coherent town planning along aesthetic lines, perhaps for the first time since antiquity." Official regulations governing the size of the palaces facing the square date from 1298. The famous square is dominated by the Palazzo Pubblico, the town hall. With growing prosperity and an emerging sense of civic pride, town halls such as Palazzo Pubblico often became a show-piece of the cities' growing confidence. In the cities of northern Italy, this development started early and many Gothic town halls and other civic monuments have to a large extent survived to this day.
