Erfurt Cathedral, dedicated to St. Mary, is a late Gothic cathedral which replaced the church built on this site for Bishop Boniface in 742. Martin Luther was ordained in the cathedral in 1507.
The architecture of the Erfurt Cathedral is mainly Gothic and stems from around the 14th and 15th centuries. There are many things of note as far as the architecture is concerned, not least the stained glass windows and furnishings of the interior of the cathedral. The central spire of the three towers that sit aloft the cathedral harbours the Maria Gloriosa which, at the time of its casting by Geert van Wou in 1497, was the world's largest free-swinging bell. It is the largest existing medieval bell in the world. It is known to have purity and beauty of tone.
The cathedral houses many rare and rich furnishings and sculptures, including the tomb of the bigamous Count von Gleichen, accompanied by both of his wives, a stucco altar, a bronze candelebra of Romanesque antiquity called Wolfram, the oldest free standing cast work in Germany, and, out on the porch, several statues of the Wise and Foolish Virgins.
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.
