CORBEIL, a town of northern France, capital of an arrondissement in the department of Seine-et-Oise, at the confluence of the Essonne with the Seine, 21 m. S. by E. of Paris on the Orléans railway to Nevers. Pop. (1906) 9756. A bridge across the Seine unites the main part of the town on the left bank with a suburb on the other side; handsome boulevards lead to the village of Essonnes (pop. 7255), about a mile to the south-west. St Spire, the only survivor of the formerly numerous churches of Corbeil, dates from the 12th to the 15th centuries. Behind the church there is a Gothic gateway. A monument has been erected to the brothers Galignani, publishers of Paris, who gave a hospital and orphanage to the town. Corbeil is the seat of a sub-prefect, and has tribunals of first instance and commerce and a chamber of commerce. It has important flour-mills, tallow-works, printing-works, large paper-works at Essonnes, and carries on boat and carriage-building, and the manufacture of plaster. The Decauville engineering works are in the vicinity. There is trade in grain and flour.
From the 10th to the 12th century Corbeil was the chief town of a powerful countship, but it was united to the crown by Louis VI.; it continued for a long time to be an important military post in connexion with the commissariat of Paris. In 1258 St Louis concluded a treaty here with James I. of Aragon. Of the numerous sieges to which it has been exposed the most important were those by the Huguenots in 1562, and by Alexander Farnese, prince of Parma, in 1590.
