Together with the cloister and the mortuary, the two-aisled Eichstätt cathedral is regarded as one of the most important medieval monuments in Bavaria. The first Roman Catholic cathedral of Our Lady and Sts. Willibald and Salvator was built in the 8th century. It was destroyed during the Hungarian invasions but the church preserved. Parts of this church have been preserved in the masonry.
The current cathedral has parts built between the 11th century and the 16th century. Bishop Heribert (1022-1042) started the construction in Carolingian-Ottonian style and bishop Gundekar II inaugurated the cathedral in 1060.
The Gothic west choir dates from 1250-1270. The east choir was reconstructed in the late 14th century. The Roritzerkapelle (1463-1480) and cloister (1410) where added later.
The west façade was restored in Baroque style in 1716-1718 and the pulpit was made in 1720. The rococo altar dates from 1745.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
