Château de La Celle-Guenand was originally founded as a monastery in the 10th century. Later in the 15th century it was reconstructed as a castle. The first known lord of this medieval château was Antoine de Guenand. From the 16th century until 1780 the estate was held by the Coutance family.
Religious conflict in 1779 had led to the removal of the pastor of La Celle-Guenand and the two parishes were merged, to be known as La Celle-Guenand. Jean Cantineau de Commacres lorded over the castle of La Celle-Guenand until 1785 the last years of the French monarchy. Followed by Pierre Gaullier to midway through the French Revolution until 1794.
The château was restored in the 17th century as a private Residence and additional outbuildins were built in the 19th century. Today it functions as a Bed & Breakfast hotel.

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.
