The lords of Beaugency attained considerable importance in the 11th, 12th and 13th centuries; at the end of the 13th century they sold the fiefdom to the Crown. Afterward it passed to the house of Orléans, then to those of Dunois and Longueville, and ultimately again to that of Orléans. The city of Beaugency has been the site of numerous military conflicts. It was occupied on four separate occasions by the English. On June 16–17, 1429, it was the site of the famous Battle of Beaugency, when it was freed by Joan of Arc. Beaugency also played an important strategic role in the Hundred Years´ War.
The 36m high square tower of Château of Beaugency was built in the 12th century. In the 1530 cardinal Le Longueville ordered bo enlarge the keep as a larger castle. It was burned by the Protestants in 1567 and suffered extensive damage to the walls, the castle, and the church.

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.
