Loches is a town and commune in France, capital of an arrondissement in the département of Indre-et-Loire, 29 miles southeast of Tours by railway, on the left bank of the Indre River.

The town, one of the most picturesque in central France, lies at the foot of the rocky eminence on which stands the Château de Loches, the castle of the Anjou family, surrounded by an outer wall 13 ft./4 m. in circumference, and consisting of the old collegiate church of St. Ours, the royal lodge and the donjon.
The church of St. Ours dates from the 10th century to the 12th century; among its distinguishing features are the huge stone pyramids surmounting the nave and the beautiful carving of the west door.
The royal lodge, built by Charles VII of France and once used as the subprefecture, contains the tomb of Agnès Sorel and the oratory of Anne of Brittany. It was here on 11 May 1429 that Joan of Arc arrived, fresh from her historic victory at Orleans, to meet the king.
The donjon includes, besides the ruined keep (12th century), the Martelet, celebrated as the prison of Lodovico Sforza, Duke of Milan, who died there in 1508, and the Tour Ronde, built by Louis XI of France and containing the famous iron cages in which state prisoners, including according to a story now discredited, the inventor Cardinal Balue, were confined.
Loches has an hôtel-de-ville and several houses of the Renaissance period.
On the right bank of the Indre, opposite the town and practically its suburb, is the village of Beaulieu-lès-Loches, once the seat of a barony.
