History: In the 10th century, Eudes I, Count of Blois, built a castle on the hills. Of the old building, only the so-called Agar Tower, or keep, remains, with some wall removals. The current castle, set at right angles, was rebuilt in the 16th century by the Beauvilliers. The north facade is divided by two brick and stone pavilions. The attic is decorated with pedimented dormers. To the south, in the main courtyard, the two buildings intersect at right angles. They are pierced by cruciform mullioned windows, separated by pilasters and bands on which figures are sheltered in small niches. Stone dormers with pinnacled and shell pediments adorn the roofs. A modern polygonal tower, outside the building, connects the two main buildings. It is highly decorated with pilasters and twin columns. The west pavilion is the most richly decorated. A frieze decorated with Italianate medallions supports an openwork balustrade. The ruins of the original castle are located opposite the current castle. The building was extensively restored in the 19th century.
