The parish and pilgrimage church of Bad Deutsch-Altenburg is a Romanesque-Gothic three-aisle pillared basilica with Gothic choir and west tower, which was built in around 1050 in Bad Deutsch-Altenburg in four construction phases. The Roman Catholic parish church has the patronal feast of the Assumption of Mary and belongs to the Deanery Hainburg of the Archdiocese of Vienna. The church is a listed building and represents an important monument of medieval architecture in Austria. A predecessor church was probably built by King Stephen I of Hungary. It is assumed it was destroyed in armed conflicts with the Hungarian king Andreas I in 1050. In 1051, Emperor Heinrich III planned or raised documents. German Altenburg to the Reichspropstei (Kollegiatstift) of the Hungarian Mark . In 1058 the seven-year-old Roman-German King Heinrich, son of Heinrich III. and later the emperor, his mother Agnes von Poitou the presumably newly built three-aisled basilica "with everything that his father, Emperor Heinrich (III.) had intended, as well as all accessories and all income with the right to dispose freely". In 1213, the owners of the rule of Deutsch-Altenburg, Alban and Johann Doerr (Dörr), a priest, initiated the construction or expansion of the church and determined church construction as a burial place for the family. Around the middle of the 14th century, the west tower presented was built with the brick octagonal tower helmet and presumably the choir with the sacristy attached to the north or the end of the 14th century. After the relocation of the castle from Bad Deutsch-Altenburg to Hainburger Schlossberg (Heimenburg) around 1050, where the former Martinskirche was built on the high terrace and Hainburg had an up-and-coming city formation process, the Marienkirche in Bad Deutsch became around 1260 - Altenburg a branch church of Hainburg. In the year 1725 the German-Altenburger church got the status of a parish church again. In 1585 and 1683 fires damaged the church and in the fire on August 15, 1774 the tracery and buttresses were largely destroyed. Around 1862 the church building was in a ruinous state and as a result a profound renovation took place, which led architect Richard Jordan from 1897 to 1900 or 1906 and was completed in 1911. The three-aisled, basilica nave has six bays . The side walls of the main aisle are supported by ten solid, square pillars and are opened to the side aisles by arched arcades. The basilica was originally covered with a flat roof. In the first half of the 14th century, a ribbed vault was pulled in and at the end of the 16th / 17th centuries. Century a cross ridge vault on the four western central nave yokes. A Romanesque chapel, which originally had its own west entrance, is attached to the southern nave over a length of two bays. The high gothic , two-bay choir with 5/8 end was built in place of the Romanesque nave and is attributed to the master Michael. The choir is dated around 1400. The buttresses are four-zone and have empty statues at the top. Between the deep pillars are two- (north-facing) and four-lane (south-facing) tracery windows . On the north side of the choir, a two-storey extension with two polygonal stair towers is built along the length of the two yokes of the choir in the west. It contains the sacristy on the lower floor and an oratory on the upper floor. A Gothic tower is almost free-standing. On the outside of the floor plan, a square with multi-zone, deep, high buttresses. In the upper area there is a free octagon with a gable wreath and at the end a brick octagonal helmet.
