The house "Le Numéro Un" dates from the 14th century and is located in the heart of Caylus, a village with a rich medieval heritage in Tarn-et-Garonne, 20 km north-east of Caussade, between Cahors and Montauban. This house is typical of the South-West where the common rooms are on the first floor, the ground floors being reserved for shops. This stone house, where it is cool in summer, has no garden or terrace; it is a real medieval house and at the time there was no notion of a garden.
