The Saint-Philbert-de-Grand-Lieu abbey was constructed around 815 on the lands of a former estate called Déas, which were given to the monk Saint Philibert in the 7th century. It was affiliated with the Abbey of Noirmoutier and served its needs. The construction was authorized by Louis I, the son of Charlemagne. This location was chosen because it was more protected from Viking raids, being further inland. Indeed, the Abbey of Noirmoutier had been attacked by the Normans multiple times during the first half of the 9th century.
During the 14th century, a wooden bell tower was erected above the entrance porch of the abbey. During the religious wars in the region, the Huguenots also caused damage to the site. They notably damaged the choir, the porch, and the bell tower. In the 17th century, the church became a parish church. Later, during the French Revolution, the abbey was sold as national property in 1791. During the Vendean uprisings, the building was used by the republicans as a fodder shed and a munitions depot.
After the construction of the new parish church in 1869, the abbey served as a covered market, and the cracked walls had to be reduced in height by 3 meters. However, the discovery of the tomb in 1865 eventually renewed interest in the site, and restoration work was carried out between 1898 and 1904. Consequently, the abbey has been classified as a historical monument since 1896, even though it was no longer in use. It was only in 1936 that it was returned to religious use. In the same year, a celebration marked the 1100th anniversary of the transportation of the relics to the town, and a relic of Saint Philibert was placed in the sarcophagus. The monument is now open to visitors, with approximately 9,000 visitors per year. In addition to tours of the building and gardens, artistic and cultural exhibitions are held within the abbey. Religious ceremonies are occasionally celebrated, including the 'Feast of Saint Philibert' with a vigil and a patronal Mass.
The abbey is predominantly in the Carolingian style, but modifications over time have incorporated elements from other styles, including Romanesque. The building has also undergone changes in its visual appearance, both on the exterior and interior.

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.
