Origin and history
The Château de Saint-Michel, located in the rural commune of Saint-Michel (Loiret), is a building whose origins date back to at least the thirteenth century under the name of the Motte Boulain. At that time, he probably already adopted a quadrangular plan surrounded by moat, typical of medieval fortifications. The oldest remains still visible today, such as the northwest wing, date back to the 15th century, with typical frames of this period. The dovecote, of circular plan, could also date from that time, although its exact construction remains uncertain.
In the 16th century, the castle suffered the violence of the Wars of Religion: looted in 1562 and destroyed in 1576, it was partially rebuilt before 1591, as evidenced by the castle of entry. The latter, raised on three levels, includes a brick vaulted passage and floors intended for housing. The original drawbridge has since been replaced by a dormant bridge. The moat and dove, with bolts and a pan-wood staircase, are typical defensive and agricultural elements of the seigneurial estates of the time.
In the 19th century, the castle underwent major changes: the southwest wing was raised and drilled, while the northeast wing was shot down around 1850. On that date, the building lost part of its original structure, retaining only the chestnut, the north tower (transformed into a dovecote), and some 16th and 18th century buildings. An 18th century barn could also belong to the whole. These changes reflect the adaptation of castles to aristocratic or agricultural residences after the Revolution.
The castle was listed in the Inventory of Historic Monuments in 1989, for its entrance chestnut, moats, doves, and eastern turret. These protections highlight its architectural and historical interest, mixing medieval heritage and modern transformations. Today, the site remains a private property, witness to social and military developments in the Gâtinais region, between Orléans and Pithiviers.
The village of Saint-Michel, rural and sparsely populated (151 inhabitants in 2023), retains this heritage as the only protected monument. Its history is related to the family of Longau Saint-Michel, the last known owner, and to the feudal and post-revolutionary organization of the Loiret. The castle thus illustrates the transition between medieval fortress and seigneurial residence, in a territory marked by agriculture and religious conflicts.
The available sources (Wikipedia, Monumentum) confirm these elements, without further specifying the contemporary uses of the site (visits, events). Its current state and accessibility are therefore partially documented.
