There are records that there was a church at this location of current St Mary's Church before the Norman conquest of Wales as it is mentioned in Domesday Book and by a charter from King John of England. However, there is nothing surviving in the current church building from that period. This is reportedly because of Augustinian canons from Llanthony Secunda visited and built the church on top of the older church that was dedicated to St Bride dating from around AD 900 at the behest of Walter of Gloucester after the construction of Caldicot Castle. The earliest part of the church is the base of the tower, which comes from the 14th century, along with the nave and chancel, which was part of an enlargement programme at the time. The tower was not fully completed until the 16th century.
In the 1850s, the 15th-century north aisle was rebuilt by Henry Woodyer, as well as most of the stained glass windows being replaced. In 1905, the chancel was refitted and many of the Victorian additions were changed.

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.
