Largest groups of immigrants by 1 January 2021 : Architecture Romanesque and Gothic The Romanesque and Gothic churches, the monasteries and the early carcass houses dominated the medieval city for a long time. The Cathedral of Archbishop Conrad of Wittelsbach was the largest basilica north of the Alps. The choir of the Franciscan Church, construction was begun by Hans von Burghausen and completed by Stephan Krumenauer, is one of the most prestigious religious gothic constructions of southern Germany. At the end of the Gothic era Nonnberg Abbey, the Margaret Chapel in St Peter's Abbey, St George's Chapel, and the stately halls of the "Hoher Stock" in Hohensalzburg Fortress were constructed. Renaissance and baroque Inspired by Vincenzo Scamozzi, Prince-Archbishop Wolf Dietrich von Raitenau began to transform the medieval town to the architectural ideals of the late Renaissance. Plans for a massive cathedral by Scamozzi failed to materialize upon the fall of the archbishop. A second cathedral planned by Santino Solari rose as the first early Baroque church in Salzburg. It served as an example for many other churches in Southern Germany and Austria. Markus Sittikus and Paris von Lodron continued to rebuild the city with major projects such as Hellbrunn Palace, the prince archbishop's residence, the university buildings, fortifications, and many other buildings. Giovanni Antonio Daria managed by order of Prince Archbishop Guido von Thun the construction of the residential well. Giovanni Gaspare Zuccalli, by order of the same archbishop, created the Erhard and the Kajetan church in the south of the town. The city's redesign was completed with buildings designed by Johann Bernhard Fischer von Erlach, donated by Prince Archbishop Johann Ernst von Thun. After the era of Ernst von Thun, the city's expansion came to a halt, which is the reason why there are no churches built in the Rococo style. Sigismund von Schrattenbach continued with the construction of "Sigmundstor" and the statue of holy Maria on the cathedral square. With the fall and division of the former "Fürsterzbistum Salzburg" (Archbishopric) to Upper Austria, Bavaria (Rupertigau) and Tyrol (Zillertal Matrei) began a long period of urban stagnancy. This era didn't end before the period of promoterism (Gründerzeit) brought new life into urban development. The builder dynasty Jakob Ceconi and Carl Freiherr von Schwarz filled major positions in shaping the city in this era.
