Maltese Church (Malteserkirche)
The Church of Saint John the Baptist, or Malteserkirche, is one of the most important sites in Vienna. Its history is invariably linked to that of the Maltese Order, after which it is named.
St. Peter's Abbey (Stift Sankt Peter)
St Peter's Abbey was founded in 696 by Saint Rupert at the site of a Late Antique church stemming from the first Christianization in the area in the days of Severinus of Noricum.
Salzburg Cathedral
The cathedral is very much the centerpiece of Salzburg. Here, there is much to discover: the baptismal font, the crypt, the art installation “Vanitas”, as well as the chest containing relics of Saints Rupert and Virgil. In addition, many secrets are associated with the seven bells as well as the three entrance doors. If you take a close look, you will even find 370-year-old graffiti scratched into the marble entranceway. (https://www.salzburg.info/en/sights/churches-cemeteries/salzburger-cathedral)
Franciscan Church (Franziskanerkirche)
The Franciscan Church is presumably even older than the cathedral, its construction ascribed to St. Virgil. And like practically all of Salzburg’s houses of worship, it was also ravaged by fire.
St. Nicholas' Church
The origin of the church dates back to the 12th century, with the construction of a chapel for marketers in the Brussels markets.
Saint-Josse Church (Sint-Joostkirk)
In 1361 a chapel was built in the hamlet of 'Ten Node' which depended on the chapter of St. Gudula.
