built. In fact, few such projects were put into practice in Europe as new cities were prohibitively costly and existing urban areas, with existing churches and palaces, could not be demolished. Only in the Americas, where architects often had a clean space to work with, were such cities possible, as in Lima (Peru) or Buenos Aires (Argentina). The earliest Baroque ideal city is Zamość, built north-east of Krakow (Poland) by the Italian architect Bernardo Morando (-1600), being a centralized town focusing on a square with radiating streets. Where entire cities could not be rebuilt, patrons and architects compensated by creating spacious and symmetrical squares, often with avenues and radiating out at perpendicular angles and focusing on a fountain, statue or obelisk. A good example of this is the Place des Vosges (formerly Place Royale), commissioned by Henry IV probably after plans by Baptiste du Cerceau (1545-1590). The most famous Baroque space in the world is Gianlorenzo Bernini's St. Peter's Square in Rome. Similar with ideal urban planning, Baroque gardens are characterized by straight and readapting avenues, with geometric spaces. Rococo The name Rococo derives from the French word rocaille, which describes shell-covered rock-work, and coquille, meaning seashell. Rococo architecture is fancy and fluid, accentuating asymmetry, with an abundant use of curves, scrolls, gilding and ornaments. The style enjoyed great popularity with the ruling elite of Europe during the first half of the 18th century. It developed in France out of a new fashion in interior decoration, and spread across Europe. Domestic Rococo abandoned Baroque's high moral tone, its weighty allegories and its obsession with legitimacy: in fact, its abstract forms and carefree, pastoral subjects related more to notions of refuge and joy that created a more forgiving atmosphere for polite conversations. Rococo rooms are typically smaller than their Baroque counterparts, reflecting a movement towards domestic intimacy. Even the grander salons used for entertaining were more modest in scale, as social events involved smaller numbers of guests. Characteristic of the style were Rocaille motifs derived from the shells, icicles and rock-work or grotto decoration. Rocaille arabesques were mostly abstract forms, laid out symmetrically over and around architectural frames. A favourite motif was the scallop shell, whose top scrolls echoed the basic S and C framework scrolls of the arabesques and whose sinuous ridges echoed the general curvilinearity of the room decoration. While few Rococo exteriors were built in France, a number
