The Liebfrauenkirche (German for Church of Our Lady) is, along with the Cathedral of Magdeburg the earliest Gothic church in Germany and falls into the architectural tradition of the French Gothic cathedrals. It is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site.
A Roman double church originally stood here. The southern portion was torn down around 1200 and completely replaced by the Early Gothic Church of Our Lady (Liebfrauen). The exact date of the start of construction can no longer be determined, however a painted inscription inside on a column in the church reads: 'The construction of this church was started in 1227 and ended in 1243'. However, it is currently thought construction began in 1230 by Archbishop of Trier Theodoric II.
Around 1260, the building was probably finished. In 1492, a high peak was placed on the central tower, which was named because of its high technology and degree of craftsmanship perfection. The high peak can be seen on the city dating, but was destroyed in a storm on Heimsuchungstag (July 2) in 1631. Subsequently a hipped roof emplaced, which was destroyed in the Second World War. It was first replaced in 1945 by a roof and then by a steeper one in 2003.
A special feature of the basilica is its atypical cruciform floor plan as a round church, whose cross-shaped vaulting with four corresponding portals in rounded niches is completed by eight rounded altar niches so that the floor plan resembles a twelve-petaled rose, a symbol of the Virgin Mary, the rosa mystica, and reminiscent of the twelve tribes of Israel and the Twelve Apostles. The apostles as well as the twelve articles of the Apostle's Creed are painted on the twelve supporting columns, completely visible only from one spot marked by a black stone.
Though nothing above the surface is Roman any longer, but there are extensive excavations (not open to the public) underneath the church and several of the Gothic pillars stand on top of Roman column foundations.
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.
