Italy, Siena, Water Reservoir in the Fontebranda Fountain, Look from Right Arch

Fontebranda is one of the medieval fountains of Siena. The first mention of a fountain was in 1081, and then it was finally rebuilt in its present form in 1246 by the Guild of the Wool-makers.
The crenellated roof spans a tank fed by water traveling for kilometers to reach the city. The structure was so large, due to multiple use: to get drinking water for men and, separately, for animals, and to wash clothes, especially the textiles made by Arte della Lana (Guild of Wool-makers).
