[1] L'Isle Castle was built in 1696 by Charles de Chandieu, lieutenant general of the Swiss Guards of Louis XIV, on plans by Jules Hardouin-Mansart, nephew of the great François Mansart.

After the hands of different families, it was bought by the municipality of L'Isle in 1876 which transforms it into school classes and as home town.

[2] L'Isle Castle draws a U-shaped plan, between courtyard and garden, with a main building, where are the reception rooms and apartments for teachers and two wings containing services (kitchen, pantry, servants' rooms) and secondary local (archives, library, attic).

In French-speaking Switzerland, the castle of L'Isle is the first regional example of French classicism and is a key milestone in the dissemination of this current.

After its renovation, different parts of the vaulted and paved spaces are an ideal place for cultural and friendly activities.
