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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
