Maillezais Cathedral was originally part of the Abbey of Saint-Pierre. It was constructed in the 15th century, and the cathedral and its associated structures were abandoned by the late 17th century. The ruins include the cathedral itself, along with a refectory, dormitory, kitchen, cellars, turrets, and ramparts.
The history of Maillezais Cathedral dates back to the 10th century when Countess Emma and her husband, William IV, Duke of Aquitaine, discovered the ruins of a chapel dedicated to Saint Hilaire during a hunting expedition. They contributed to the reconstruction, and the new church was consecrated in 989. The abbey was moved to Maillezais in 1010, and it became a significant religious institution.
In 1317, Maillezais was elevated to the status of a diocese, with Saint-Pierre Cathedral serving as its seat. The cathedral became a center of intellectual pursuits, with figures like François Rabelais teaching there in the early 16th century.
However, during the Reformation and the subsequent Wars of Religion, the cathedral was destroyed in 1562. It was later fortified by Agrippa d'Aubigné, a Protestant, and used as a stronghold by the Protestants for several decades.
The cathedral changed hands between Catholics and Protestants multiple times before returning to Catholic control in 1619. In 1648, the Bishopric of Maillezais was transferred to La Rochelle, and the monastic community at Maillezais was abandoned in 1666.
After the French Revolution, the cathedral was sold as national property and later returned to the people in 1840. It was designated a historical monument in 1924. Restoration efforts began in the late 20th century.
Today, the ruins of Maillezais Cathedral bear witness to its rich history, with elements of Romanesque and Gothic architecture still visible. Excavations have revealed foundations of various buildings, including a kitchen, refectory, dormitory, and chapter house, providing insight into the abbey's daily life.

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.
