The chestnut tree of one hundred horses is a unique landmark of Sicily, situated in the village of Sant'alfio, on the Eastern slope of mount Etna in 8 km from the crater of the volcano. Scientists believe this chestnut the biggest and the oldest in the world – it is from 2 to 4 thousand years. And in the Guinness Book of Records he made as a tree with the largest trunk girth: in 1780 the circumference of the barrel was almost 58 metres! The height of the tree is 22 meters. Despite the fact that chestnut has three shaft height 13, 20, and 22 meters, they all have one common root.

This tree is repeatedly mentioned in the Italian poems and songs. Even the origin of its name has a legend that one day the Queen, caught in a storm while hunting, took refuge under the canopy of chestnut, together with hundreds of accompanying knights. The storm lasted until the evening, and all the retinue sat under the tree. Hence the romantic name – the Chestnut tree of one hundred horses. It is not known what the Queen in question - perhaps it was Giovanna I of Aragon (1455 - 1517). According to another version – English Empress Elizabeth, the third wife of Frederick II. Finally, some suggest that we are talking about the Queen of Naples Giovanna I (1328 - 1382), the name which is connected with the notorious Sicilian Vespers. But, most likely, all of these legends are just a figment of people's imagination.

About 400 metres from the Chestnut tree of one hundred horses growing another chestnut, which is about a thousand years – Chestnut-Ship, also called Chestnut St. Agatha. This tree, according to some research, is the second in age and size in Italy. Circumference of its trunk is 20 meters, the height is 19 meters.

And in the vicinity of the village of Zafferana Etnea, on the Eastern slope of mount Etna, you can see stone oak Iliç di Carrino, the age of which is also estimated to be a thousand years. It has a trunk girth at 4 meters and a height of 19 meters.
