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.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
