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.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
