St. Peter's Church is the oldest church in the Munich district. Before the foundation of Munich as a city in 1158, there had been a pre-Merovingian church on this site. 8th century monks lived around this church on a hill called Petersbergl. At the end of the 12th century a new church in the Bavarian Romanesque style was consecrated, and expanded in Gothic style shortly before the great fire in 1327, which destroyed the building. After its reconstruction the church was dedicated anew in 1368. In the early 17th century the 91 meter spire received its Renaissance steeple top and a new Baroque choir was added.
The interior is dominated by the high altar to which Erasmus Grasser contributed the figure of Saint Peter. Among other masterpieces of all periods are five Gothic paintings by Jan Polack and several altars by Ignaz Günther. The ceiling fresco by Johann Baptist Zimmermann (1753–1756) was re-created in 1999-2000.
The parish church of Saint Peter, whose 91 meters high tower is commonly known as Alter Peter - Old Peter - and which is emblematic of Munich, is the oldest recorded parish church in Munich and presumably the originating point for the whole city.
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.
