Tours Royal Castle
The Royal Castle of Tours is located in central Tours, close to the Cathedral of Saint Gatien. Until 2000 it was used to house the city aquarium, where you could see some 1500 fish of 200 different species. Currently it is being used as an exhibition centre of modern art, as well as serving as the main museum of history and archeology. Entrance is free Tuesday to Sunday from 14:00 to 18:00. A very interesting and informative experience.
