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:
From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, becoming a royal castle that was the seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman advance, and has been a key crossroad between the Mediterranean belt and the Balkan rear.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia"s rulers. The reign of his successor, Duke Trpimir I, the founder of the Croatian royal House of Trpimirović, is significant for spreading Christianity in the Duchy of Croatia. He largely expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
In March 1242 at Klis Fortress, Tatars who were a constituent segment of the Mongol army under the leadership of Kadan suffered a major defeat while in pursuit of the Hungarian army led by King Béla IV. After their defeat by Croatian forces, the Mongols retreated, and Béla IV rewarded many Croatian towns and nobles with 'substantial riches'. During the Late Middle Ages, the fortress was governed by Croatian nobility, amongst whom Paul I Šubić of Bribir was the most significant. During his reign, the House of Šubić controlled most of modern-day Croatia and Bosnia. Excluding the brief possession by the forces of Bosnian King, Tvrtko I, the fortress remained in Hungaro-Croatian hands for the next several hundred years, until the 16th century.
Klis Fortress is probably best known for its defense against the Ottoman invasion of Europe in the early 16th century. Croatian captain Petar Kružić led the defense of the fortress against a Turkish invasion and siege that lasted for more than two and a half decades. During this defense, as Kružić and his soldiers fought without allies against the Turks, the military faction of Uskoks was formed, which later became famous as an elite Croatian militant sect. Ultimately, the defenders were defeated and the fortress was occupied by the Ottomans in 1537. After more than a century under Ottoman rule, in 1669, Klis Fortress was besieged and seized by the Republic of Venice, thus moving the border between Christian and Muslim Europe further east and helping to contribute to the decline of the Ottoman Empire. The Venetians restored and enlarged the fortress, but it was taken by the Austrians after Napoleon extinguished the republic itself in 1797. Today, Klis Fortress contains a museum where visitors to this historic military structure can see an array of arms, armor, and traditional uniforms.
