a town of France, capital of a cognominal arrondissement, in the department of Indre, and situated partly on the declivity and partly at the foot of a hill, on the right bank of the Théols, 17 miles N.E. of Châteauroux, and 148 miles S. of Paris, with both of which it is connected by railway. The river is here crossed by three bridges, connecting the town with as many suburbs on the opposite bank. Issoudun was formerly a place of considerable strength, and has been subjected to repeated sieges. The fire of 1651, by which upwards of 1000 houses were destroyed, gave occasion for great improvements in the town, and to this circumstance it owes its superiority to the other towns in the centre of France. The Tour-Blanche, an erection of the twelfth century, the walls of which are 14 feet thick and 95 feet in height, and the ancient town-gate and belfry, now used as a prison, are objects of interest. The chief manufactures are woollen cloth, cotton goods, hosiery, leather, and parchment; and these, with corn, wine, wool, cattle, and timber, constitute the chief articles of trade. Pop. (1851) 13,215.
