Château de la Loyère, Heritage castle in Fragnes-La Loyère, France.

Château de la Loyère is a rectangular castle built of three U-shaped wings and flanked by square towers. The central block has a three-sided projecting pavilion to the south, fronted by a terrace aligned with the towers and reached by two staircases with diverging flights. The southwest tower is flanked by a square turret topped with a tall lantern housing a spiral staircase, the remnant of the original castle.

In the Middle Ages the seigneurie of La Loyère belonged to the Abbey of Saint-Pierre de Chalon. In 1580 it was acquired by Jean-Baptiste Beuverand, a member of an old Chalon bourgeois family. In the 17th century Jean Beuverand de la Loyère, mayor of Chalon, received the Prince of Condé there and transformed the castle. In 1845 Vicomte Armand de la Loyère gave it its present appearance.

The southwest tower displays a spiral staircase from the original medieval period, showing how fortified residences in Burgundy were built and designed. This staircase illustrates the practical building methods that craftspeople developed for such fortified structures.

The château is a private property and cannot be visited; only its exterior can be seen from the surrounding land. The town of Chalon-sur-Saône acquired the estate in 1964 and installed a leisure centre there, with cultural and sports events for young people during school holidays. The entrance gate was dismantled and re-erected in Chalon at the end of the square de l'Arquebuse.

A commemorative oak tree stands on the grounds, planted to mark the victory of Rocroy during the time when Jean Beuverand de la Loyère hosted the Prince of Condé. This tree connects a notable episode of French military history directly to the estate.
