Saint-Léger Church of Sancheville

Highlight • Religious Site

The Saint-Léger church in Sancheville existed from the 12th century, it was a single nave church. There are remains of this primitive building in four pillars of the nave, at the base of the bell tower and on the south wall.

In the 13th century, the church was rebuilt, the nave was enlarged and vaulted with ribs. The pillars of the Romanesque choir supported a tower built in the 13th century and which burned down on April 13, 1608.

In the 14th century, the main portal with buttresses was built, without a tympanum.

In the 16th century, the north aisle was built and a second portal was built, a remarkable Renaissance ensemble.

Also in the 16th century, at the same time as the vault of the north aisle, the vault of the main nave was redone in a pointed arch.

The current bell tower was built in the 17th century, replacing the burnt tower.

The frame was redone in the 17th century, as was the layout of the sanctuary.

Bonneval

Highlight • Settlement

Bonneval is a beautiful town with still-present fortifications. The old town is surrounded by a wall at the foot of which flows the Loir. This city retains many period buildings such as the Saint-Roch Gate and the King's Tower. Among its must-see attractions, the city also includes the Benedictine abbey of Saint-Florentin-et-Saint-Hilaire, many times destroyed and rebuilt during wars.

Saint-Pierre-et-Saint-Paul Church

Highlight • Religious Site

Saint-Pierre-et-Saint-Paul Church is a Romanesque building that underwent some modifications following the partial destruction of the village during the war of 1870. The oriented nave ends with a semi-circular apse and adjoins, to the north, a side aisle. Access is located in the southwest part of the nave, protected by a long canopy. A sacristy was built outside the work and communicates directly, to the south, with the apse. The aisle opens onto the nave by two large arcades. At the entrance to the choir, stand two columns with primitive capitals intended to receive an arch that was probably never built. The nave and the choir are covered with a paneled vault. Two pointed arch bays light the nave to the south. The windows of the apse and the aisle are semicircular. The west gable also includes a semicircular bay. On this side of the church, the arch of the old portal, now walled up, is still visible. An oculus has been pierced in its upper part. The roof is made of slate, as is the bell tower, erected on the western part of the roof. Inside, the decor is especially remarkable for the wall paintings from the 12th and 13th centuries that were discovered in 1939, behind the altarpiece of the sanctuary, by Father Moriceau, the parish priest. Some of them are illegible, others have been perfectly identified. These are the scenes depicting the Descent from the Cross, the Holy Women at the Tomb, the Baptism of Christ, and the Meal at Herod's. Like those in the church of Lutz-en-Dunois and the chapel of Yron in Cloyes, these wall paintings are characteristic of the artistic creation of the upper Loir Valley in the Romanesque period. For the restoration of the plaster and the renovation of the south facade of the church and the porch, the Sauvegarde de l’Art français granted a subsidy of 35,000 F in 1998.
