Foundations of the terrace and former wine storage places, these huge cellars are the imprint of the wine-growing past of the estate. The wine produced by the bishops of Tours was transported from the winepress of the castle to these cellars through an underground network. It was then kept at the ideal temperature in these three colossal cellars facing the confluence. Today, these places become part of the route of the Street Art Park and house of street art’s works.
