The Lucerne Jesuit Church is the first large baroque church built in Switzerland north of the Alps. The Jesuit order, founded by Ignatius of Loyola in 1534, were active participants in the Counter-Reformation, the Catholic fight against the birth of Protestantism. Protestant reformers such as Zwingli in Zurich and Calvin in Genevadivided the predominately Catholic Switzerland. In response, the Jesuits were called in to Lucerne by the city council in 1573 to establish a college. Ludwig Pfyffer, mayor of Lucerne, offered annual financial support to the Jesuits out of his private funds. The Jesuit College of Lucerne was established in 1577 in Ritter Palace, a building originally erected in 1557 as a residence for mayor Lux Ritter.
Construction on the associated church began in 1667. By 1673 the shell of the church and the main façade were completed. The church was consecrated in 1677, though the interior was not yet really finished. Several side altars were still missing and even the high altar was only erected four years later, due to financial problems. The onion topped towers were not completed until 1893. The vault was redecorated in the mid-18th century. The original vestments of Brother Klaus, a famous Swiss patron, are stored in the inner chapel.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
