Château de Boutavent may have been built in the 11th century, but there is no written evidence of exact date. It has been confirmed that during the 13th and 14th century, the castle belonged to the Lords of Montfort. According a legend during the 7th century the castle was the residence of Judicaël, King of Domnonée, and that it had been the place where the King and saint Éloi met. This last was sent to bring peace in a fight for borders between Bretons and French.
The castle is structured into two classical elements: a courtyard and a barnyard, separated by a deep gap. Four buildings which could be guesthouses, are on both sides of the barnyard. The fortification and elements of the barnyard can still be seen.
In the 16th century, the castle was already ruined. The circumstances of the destruction of the fortified site of Boutavent remain mysterious. Maybe it has been dismantled during the War of succession (second half of the 14th century) or in 1373, during the campaign of Bertrand du Guesclin in Brittany, but nothing proves that the castle hasn't been inhabited then.
Many local authors of the 19th century wrote about Boutavent, in particular writers like Poignand, Vigoland or Oresve. Even though these stories constitute rare stories about the site, it is impossible to retrace the entire history of the castle, as there are only a few sources.
The castle has not been searched yet but many campaigns of consolidation of the relics took place since 2006. During these campaigns, archaeological material has been found (slate, ceramic, ground pavement and glazed tiles).
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.
