The 12th century fortified church of Santa María de Ujué stands on the highest point of the town. It is a fine example of Romanesque architecture, with Gothic additions.
The church originates back to the 9th century when Iñigo Arista ordered a temple to be built next to the fortress that this king ordered to be built. This first pre-Romanesque church was demolished to erect a new Romanesque building in the 12th century under the auspices of King Sancho Ramírez. In the 14th century, Charles II ordered part of the Romanesque naves to be demolished in order to build a single Gothic building. The choir, the undertowers, the crenellated towers and the façades were also built, as well as the church was surrounded by promenades and walls. All of this gave the complex the appearance of a fortress that it still has today. Interred in the church is the heart of Charles II of Navarre.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. 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.
