Location: North-West France
The department is founded 4 March 1790, in accordance with the law of 22 December 1789. It is constituted of some old provinces of the Orleanais and of the Touraine along with a Berry’s plot (left bank of the Selles en Berry’s Cher which becomes Selles sur Cher, to Saint-Aignan). The department’s constriction in its centre and the maximum stretching out in its surface area beyond the Loir on the North and the Cher on the South is due to these tribulations.
Loir-et-Cher is a part of the modern region of Centre-Val de Loire. Adjacent departments are Eure-et-Loir to the north, Loiret to the north-east, Cher to the south-east, Indre to the south, Indre-et-Loire to the south-west, and Sarthe to the west.
Its main rivers are the Loire, on which its prefecture (capital) Blois is situated, the Loir and the Cher.
