St Tugual's Chapel dates back to the 11th century when the island was a haven for an order of Norman monks. However, there is evidence that the site has had religious significance since the 6th century. The chapel was designed in such a way that they could sit in the building's north nave without being seen by the public who would sit in the west portion of the chapel.
In the years before the Wood family took hold of the lease on the island, in 1949, the grounds around the west and south of the chapel had become overgrown and it was in their time that the churchyard come garden was made around the church.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
