The castles are:
Fougères Castle - The heir to a thousand years of history, the château de Fougères still stands on its rocky islet. The château as it stands today is one of the largest medieval fortress in Europe.
Le Bos - Built in the 17th and 18th centuries by fleet owners from Saint Malo, the Château du Bos is one of the largest “malouinières” houses. The Magons, a well-known family of navigators and merchants who lived in the area, erected it between 1715 and 1717. Le Bos represents the typical architectural style of the area of Clos-Poulet during the 18th century. - in: http://www.le-bos.fr/en/history
La Bourbansais - Built in the 16th century and refurbished in the 18th, the Château de la Bourbansais has long been renowned for its formal french gardens. It now houses a private zoo with over 500 animals,
Combourg - The castle was originally built in the 13th century, although substantially modified in the two centuries that followed. It was in 1761 that the castle was bought by the Chateaubriand family (parents of the author), subsequently being inherited by the author's older brother in 1786 - an ownership that wasn't to last long, because in the years of terror following the revolution in 1789 they were executed.
The castle is still owned by one of Chateaubriands descendants, and is open to the public where, among other things, you can see various artefacts belonging to the late Chateaubriand and rooms furnished in the style of that time. - in: http://www.francethisway.com/places/combourg.php

Montmuran - Once an imposing fortress, it is now a magnificent 14th century châtelet that has been perfectly preserved - its two drawbridges still work today.
Rochers-Sévigné - The splendid architecture of this castle dates back to the 1500 and is presently the home to a fine museum, chapel and lush French garden as well.
Vitré - Dating from the 13th century, the castle, with its pointy slate turrets, hosted the Parlement de Bretagne on three occasions in the 16th century when plague ravaged Rennes. These days it houses a museum where you can learn more about its history and the town as well as admiring the collection of 19th-century curiosities. - in: http://www.brittanytourism.com/discover-brittany/heritage/vitre
