The Abbey of Saint-Acheul was a monastery of Canons Regular in Amiens. It was founded in the 11th century on the site of an ancient church, and was suppressed in 1790 during the French Revolution. The buildings, which date to the 18th century, were taken over by a college that was entrusted to the Jesuits in 1814. They are now occupied by the private Lycée Saint-Riquier. The abbey church is used as a parish church.
An ancient church named Notre Dame des Martyrs, known as the first cathedral of Amiens, was founded in memory of Saint Firmin the Martyr. Later it became part of the Abbey of Notre Dame de Saint-Acheul. Modern historians have debated when and by whom the church was founded, but Bishop Rorico of Amiens (c. 1081–85) was confident that it was the oldest Christian building in Amiens.
The crypt under the church contains ancient tombs and bas-reliefs. It was discovered on 10 January 1697 during construction of a foundation for the main altar in the church. The monks claimed they had found the body of Saint Firmin, and said the relics in the Amiens Cathedral were not authentic. After lengthy controversy the relics in the cathedral were opened on 10 January 1715 and the 13th century inscriptions were taken to prove their authenticity. The vault of the 11th century church collapsed in 1751 and all the buildings were completely rebuilt in 1760. During the revolution the church became the parish church for the districts of La Neuville and Boutillerie. Under the Terror it was changed into stables. It was again made a parish church in 1844.
The church has a classical sober stone architecture. The interior has a 'Jesuit' style. The facade has a large door surrounded by pilasters with Tuscan-style capitals. Higher up a bay and niches are arranged between pilasters with Doric capitals that support the triglyphic entablature, on which there is a triangular pediment. Under the choir there is a vault in the place where the body of Saint Firmin was miraculously discovered. The church holds several sarcophagi and 15th century bas-reliefs relating to the history of Saint Firmin.

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.
