It is named from the rivers Indre and Loire, which unite within its limits. The Vienne and the Creuse water it in the south. In the N. districts are several arid wastes, and all over the department many extensive forests, the largest of which are those of Amboise, Loches, and Chinon. The climate is remarkable for its mildness and salubrity. The soil is in general extremely fertile. The land on both sides of the Loire is called the garden of France, and consists of a light but deep vegetable loam. Grain, hemp, flax, anise, and coriander are grown on a large scale. Fruit is very abundant, and the Tours prunes are largely exported. Much wine is made, some of which bears a high reputation. Bees and silkworms are carefully tended; game and fish are abundant. The chief industrial products are bar iron, hardware, powder, woollen cloth, silk, leather, paper, and pottery.

The department is divided into the arrondissements of Tours, Chinon, and Loches. Capital, Tours.
