The Arms of the first Lords of Tours were carved in the tympanum of the door to the dungeon which is, due to the expansion of the chateau, in the south-western corner of the courtyard.

It was lit in the early days, by a single window opening in the rib of the east wall of the chevet but was sealed off in adapting this side of the rural chapel.

The door is the same as the dungeon door.- Raymond Guinodie, History of Libourne and other towns and Villages and its Arrondissement, Volume 3, 1876 It was restored by Viollet-le-Duc in the 19th century.

Behind the curtain of tall trees there are cellars arranged with the utmost care, storehouses packed with wine, presses, and vats prepared to receive the harvest, stables for horses and oxen, sheds for wagons, ploughs, and all the tools of the winemaker.

Each vine, towards the base of the stock where the branches are fastened and there are new shoots for the year, is surrounded by a belt of rough clusters of blue-black velvet that indicates impending maturity and the next harvest.- Bertall, 1 October 1876 The Château des Tours has gradually fallen into disrepair, and it needs urgent restoration work.
