The Château de la Hunaudaye was built by Olivier Tournemine around 1220. In that time, this castle protected the eastern border of the Penthièvre (Lamballe’s area), which was involved in a feud with the Poudouvre (Dinan’s area).
The castle was destroyed in 1341, during the war of Brittany Succession, a civil war that ravaged the Brittany dukedom during two decades. At the end of the 14th century, Pierre Tournemine started the reconstruction of the castle according to the latest military innovations, the three bigger towers and the dwellings were built in that period.
At the end of the 15th century, the Tournemine family became powerful within Brittany dukedom. By the 16th century, their seigneury represented more than 80 parishes. In addition, they owned various other lands, seigneuries and castles in the Tregor area and also others in the vicinity of Nantes.
The golden age of the castle began in the early 17th century, as the Tournemine family gently faded away. The Renaissance stairs of the western dwelling are the last elements built and the medieval castle was fitted to the new architectural standards. However, decline is on the way. The castle becomes less maintained. The lands and seigneuries are gradually sold out and the weeds begin to grow.
The castle was raided and torched during the French Revolution. By the 19th century, people used the castle as a quarry for stone and thus many of its buildings disappeared. The northern part of the castle collapsed in 1922. It was that, the French government immediatly tried to save the castle by classing it as a historical monument and by buying it out in 1930.

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.
