As soon as you get into The Holiday House “Il Chiostro del Carmine” you can access to the cloister, 400 years old, still maintaining the same architectural appealing. In the open space to the back of the convent, now used as a guest parking, it has been found the famous “Diana’s Well”. This deep and very old well, was already used in the XII century by the citizens of the area to try to find the water of the Diana’s river. The research of these waters have been an obsession for Siena during the Medieval time. Infact the low availability of this natural resouce had an impact on the destiny of Siena and its citizens. Without any doubt the historians have determined in this dig the well that was supposed to lead to the waters of the mythical underground Diana’s river. In this sense we can find traces in Dante’s Play, infact, the street where “il chiostro del Carmine” opens his doors, it is called “Via della Diana”.
