Origin and history

Keriolet Castle, located near Beuzec-Conq (now Concarneau, Finistère), is a neo-Gothic building built in the second half of the 19th century. It replaces a 16th century mansion, a successor property of the Kériollet, Trédern and Kersalaun families. In 1861, Count Henri Chauveau, a former diplomatic courier who became noble by marriage with the Russian princess Zénaïde Youssoupoff, bought the estate to run for local elections. Under the direction of architect Joseph Bigot, the castle was completely rebuilt between 1866 and 1884, inspired by the castles of Blois, Rustephan and the priory of Locamand. The facades combine Breton (hermine), French (fleurs de lilies) and Russian (stars), reflecting the singular history of its owners.

Princess Zénaïde Youssoupoff, widow and exiled from Russia, finances sumptuous works, including a chapel (destroyed in 1971), a park decorated with statues (Velléda, Vercingetorix, Anne de Bretagne) and outbuildings such as the Marie-Jeanne Tower. Upon the death of the Count in 1882, Zenaïde left the estate to the Finistère department, provided that it remained intact. Opened to the public after his death in 1893, the castle houses Camille Bernier's collections of paintings. However, the heirs Youssoupoff, fleeing the Russian revolution of 1917, began a trial in the 1950s to recover the estate, arguing that the will was not respected.

In 1956, Prince Felix Youssoupoff won and recovered Keriolet, which he quickly sold. The castle deteriorated: the chapel was destroyed in 1971, the 1987 storm carried the roof, and decorative elements were stolen. Saved by Christophe Léveque in the 1990s, the castle was restored and reopened to the public, even hosting the Astropolis festival between 1997 and 2001. Today it is privately owned and bears witness to a unique mixture of Breton history, French political ambitions and Russian aristocratic heritage, classified as a Historic Monument since 1984 for its facades, roofs and guard room.

Keriolet's architecture draws on Breton and French Gothic models, such as the château de Blois (bas-relief de Louis XII) or Rustephan (tourelle-escales), while the park includes references to the history of Brittany (statue d'Anne de Bretagne) and France (Jeanne d'Arc, Du Guesclin). The interiors, now partially disappeared, included a carved ceiling inspired by the capitular hall of Reims and stained glass windows representing the kings of France. The estate, initially vast, was fragmented in the 20th century, losing some of its furniture and land. Despite these vicissitudes, Keriolet remains a remarkable example of the neo-Gothic Breton, marked by the cultural eclecticism of its sponsors.
