VINCENNES, a town of France, in the department of Seine, 2 miles E. of Paris. It stands on the northern edge of the park or wood of Vincennes, and is a well built town. The only building of any importance here is the old castle, a large and regular fortress in the form of a parallelogram, with walls, moat, and towers. It has been greatly altered at various periods, and now consists of a mixture of ancient and modern buildings. Many of the French kings resided here, and it was long used as a state prison. Condé, Diderot, Mirabeau, and other distinguished men have been confined here; and the Duc D'Enghein was shot in the moat by order of Napoleon, 21st of March 1804. A monument has been erected to him in the beautiful Gothic chapel of the castle. There are now here a large armoury and depot of artillery. Pop. 8451.
