Easy and very beautiful hike following the river and pond; however, be careful at the roundabout on the way back to Lucé.

On the trail of Véloscénie, a peaceful corner by the water for a picnic between the weeping willows. Quiet path, little passage and stone bench.

Built in 1768, the castle was extended a century later, then used as a boarding school around the 1950s. The castle was bought in 2004 by the Boulard family who restored it. Since then, it is possible to rent it for seminars or weddings. A 22-hectare park surrounds two guest rooms and is home to wallabies and some unusual animals.

It was in the 4th century that an oratory in honor of Saint George, martyred around the year 303, was built. Two centuries later, a chapel replacing the oratory was built by the monks of the abbey of Saint-Père-en-Vallée in Chartres. This abbey was located behind the Saint-Pierre church, on the current site of the Lycée Marceau. During the thirteenth century, between 1250 and 1270, the chapel gave way to a church. The parish - which will later become the commune - of Saint-Georges is constituted and becomes the capital of a seigneury of the chapter of Chartres. The church froze its architecture, as we know it today, in the sixteenth century around 1500, when it was enlarged by the construction of the South Chapel. source: wikipedia
