Basilica of St. Donatian and St. Rogatian is a Roman Catholic minor basilica in Nantes. The church building stands on the site of an ancient Gallo-Roman villa. Excavations in 1873 brought to light an ancient pagan cemetery, a pit in the center of the apse containing 27 nails assigned to the coffins of the two martyrs and reveal that four church buildings were successively below the basilica.
The promulgation of the Edict of Constantine, nine years after the death of the martyrs, sees developing a cult around the bodies of two brothers as martyrs, first dislocated on the rack, whipped and driven out of the city not far from the current basilica where an executioner speared them in the throat and then beheaded them. According to tradition, their bodies are placed, 21 years after their death, in a gray marble sarcophagus, measuring 2.25 meters long and 75 centimeters wide. The relics then attract pilgrims. The first church was built in the tradition of family ownership of Nantes saints to 490.
The Norman invasions destroyed the first building, but once peace returned, a new church building was built around the year 980. However, according Dubuisson-Aubenay, the primitive sanctuary remnants still exist in the 17th century, including an ancient apse.
16 March 1739, the foundation stone of the reconstruction is by Jean-Marie de Trevelec, adviser to the Parliament of Brittany and his wife Françoise Charrette.
Transformed into a hospital during the French Revolution, it was sold in 1796. Once the church returned to use for worship in 1802, the missing parts were reconstructed from 1804, giving birth to a larger church of cruciform shape, consecrated by Bishop Duvoisin 28 March 1806.
The current building dates from the 19th century. It is dedicated to St. Donatian and St. Rogatian. It was elevated to the rank of minor basilica on 14 March 1889.

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.
