The Oiselinière estate was, before the French Revolution a 'Seigniory'. It is mentioned as early as 1335 in the charter 'Les Actes'. It spreads over the districts of Gorges and Clisson, and under the feudal system depended on the Seigneurs of Clisson and Pallet. For 643 years, this Seigniory only changed families four times: Maurice le Meigen was the owner, then in 1460 one of this descendants through allegiance, Claude Grézeau took over. His family sold the seigniory of the Oiselinière to Jean Goulet de la Fosse de Nantes in 1613. Louis de la Bourdonnaye acquired the property in 1658. Then in 1767, the seigniory was sold to the ancestors of the Aulanier family (This family made a great contribution in the Second World War, Oselinière being a hotbed of resistance).
The castle is a villa built in Italian style between 1822 and 1835 to enclose a square courtyard dated from the 17th century. The villa, the outbuildings, the orangery and the gallery of 'Les Illustres' are included in the inventory of historical monuments since 1997 and are cited as reference in the inventory 'Clisson or return to Italy.'
To the west of the villa, near the orangery stands a set of architectural interest with six niches on its main facade which are made of circular brick and adorned with busts of famous men. From left to right, we can recognize Olivier de Clisson, Conde, Duquesne, Jean Bart, and Bayard Duguesclin.
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.
