The Kapuzinerkloster are located on a mountain facing the old town if Salzburg: the Kapuzinerberg mountain, named after the abbey. There are two scenic routes leading to it: via the Imbergstiege off Steingasse and the romantic St. Johannes Church; this little church that is often missed by visitors is on one of Salzburg′s most picturesque spots and was recorded for the first time in the early 14th century.
Prince Archbishop Wolf Dietrich von Raitenau built the Kapuziner Abbey and church to accommodate the monks of the Kapuziner order, when he called them into Salzburg in 1594. The buildings were erected on the site of the Trompeterschlössel ('trumpeter castle'). The northern wall of the Kapuziner Church is the only remain of this castle.
It was extended and decorated in Baroque style under Prince Archbishop Max Gandolf. 'Imberg' was the former name of the Kapuzinerberg.
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.
