Château-Renault is located on the Far-West of the Gâtine Tourangelle plateau, next to the Loir-et-Cher department and at the confluence of two rivers : The Gault and the Brenne.

Located in the North of A10 highway, the town of Chateau-Renault is equidistant to the cities of Tours and Vendôme and can be reached on train services on the Tours-Paris or Tours-Vendôme lines.

In the early part of the century a loyal member of the court of the Count of Blois was charged by the construction of a defensive structure (most likely a simple wooden tower) on the site of the present chateau.

It was under the new management that land was donated for the construction of a chapel and a small settlement at the foot of the castle site.

High levels of calcium carbonate in the water gave the leather produced there a thick, resistant nature and the arrival of the railway in 1867 ensured that the product had access to a market.
