St. Michael's church in Aachen was built for the Jesuit Collegium in 1617-1628 and is now a church of the Greek Orthodox Metropolis of Germany.
With the dissolution of the Jesuit Order in September 1773 the church was closed and converted into a granary during the French period, later it was used as a parish church. In 1987 the Greek Orthodox community of St. Dimitrios which was found in 1963 purchased the building. Beside Orthodox services also ecumenical services are held in it. Recently, due to its good acoustics and location the church enjoys an increasingly popularity by choirs and orchestras.
The three-galleried basilica was built between 1617 and 1628, and the tower between 1658 and 1668 which this is oriented to the northwest and is located at the front of the choir. The building is stylistically attributed to the Rhine mannerism. Due to the many similarities of the design and the execution of both the Jesuit church in Molsheim and Church of the Assumption in Cologne the church is attributed to the Baroque architect Christoph Wamser. However, the vertically structured facade of the Renaissance-building remained unfinished until 1891 when the historistic architect Peter Friedrich Peters added some parts. In the niches there were once small statues, but they were stolen a few years later. The now empty niches are illuminated today. During the Second World War the building was badly damaged, the reconstruction of simplified roof was held until 1951. Orthodox paintings in the interior were added in 1997 and 2002 by the artist Christophanis Voutsinas.
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.
