Despite the fact that the barrel has three chestnut height of 13, 20 and 22 meters, they all have a common root.

This tree is mentioned repeatedly in the Italian poems and songs. Even the origin of its name is a legend that one day the Queen, hitting a storm while hunting, hid under the canopy of chestnut, along with a hundred knights accompanying her. The storm lasted until the evening, and the whole entourage sat under a tree. Hence the romantic name - hundred horse chestnut. It is not known what kind of queen in question - perhaps it was Giovanna I of Aragon (1455 - 1517). According to another version - the English Empress Elizabeth, the third wife of Frederick II. Finally, some have suggested that we are talking about the Queen Giovanna I of Naples (1328 - 1382), whose name is linked to the infamous Sicilian Vespers.
