<P> In the Holy Roman Empire, the Baroque period began somewhat later . Although the Augsburg architect Elias Holl (1573--1646) and some theoretists, including Joseph Furttenbach the Elder already practiced the Baroque style, they remained without successors due to the ravages of the Thirty Years' War . From about 1650 on, construction work resumed, and secular and ecclesiastical architecture were of equal importance . During an initial phase, master - masons from southern Switzerland and northern Italy, the so - called magistri Grigioni and the Lombard master - masons, particularly the Carlone family from Val d'Intelvi, dominated the field . However, Austria came soon to develop its own characteristic Baroque style during the last third of the 17th century . Johann Bernhard Fischer von Erlach was impressed by Bernini . He forged a new Imperial style by compiling architectural motifs from the entire history, most prominently seen in his Karlskirche in Vienna . Johann Lucas von Hildebrandt also had an Italian training . He developed a highly decorative style, particularly in façade architecture, which exerted strong influences on southern Germany . </P> <P> Frequently, the Southern German Baroque is distinguished from the Northern German Baroque, which is more properly the distinction between the Catholic and the Protestant Baroque . In the Catholic South, the Jesuit church of St. Michael in Munich was the first to bring Italian style across the Alps . However, its influence on the further development of church architecture was rather limited . A much more practical and more adaptable model of church architecture was provided by the Jesuit church in Dillingen): the wall - pillar church, a barrel - vaulted nave accompanied by large open chapels separated by wall - pillars . As opposed to St. Michael's in Munich, the chapels almost reach the height of the nave in the wall - pillar church, and their vault (usually transverse barrel - vaults) springs from the same level as the main vault of the nave . The chapels provide ample lighting; seen from the entrance of the church, the wall - pillars form a theatrical setting for the side altars . The wall - pillar church was further developed by the Vorarlberg school, as well as the master - masons of Bavaria . This new church also integrated well with the hall church model of the German late Gothic age . The wall - pillar church continued to be used throughout the 18th century (e.g. even in the early neo-classical church of Rot an der Rot Abbey), and early wall - pillar churches could easily be refurbished by re-decoration without any structural changes, such as the church at Dillingen . </P> <P> However, the Catholic South also received influences from other sources, such as the so - called radical Baroque of Bohemia . The radical Baroque of Christoph Dientzenhofer and his son Kilian Ignaz Dientzenhofer, both residing at Prague, was inspired by examples from northern Italy, particularly by the works of Guarino Guarini . It is characterized by the curvature of walls and intersection of oval spaces . While some Bohemian influence is visible in Bavaria's most prominent architect of the period, Johann Michael Fischer (the curved balconies of some of his earlier wall - pillar churches), the works of Balthasar Neumann, in particular the Basilica of the Vierzehnheiligen, are generally considered to be the final synthesis of Bohemian and German traditions . </P> <P> Protestant sacred architecture was of lesser importance during the Baroque, and produced only a few works of prime importance, particularly the Frauenkirche in Dresden . Architectural theory was more lively in the north than in the south of Germany, with Leonhard Christoph Sturm's edition of Nikolaus Goldmann, but Sturm's theoretical considerations (e.g. on Protestant church architecture) never really made it to practical application . In the south, theory essentially reduced to the use of buildings and elements from illustrated books and engravings as a prototype . </P>

Why was the baroque style of architecture a favorite of the churches of the day
