Ilice Di Carrinu, Historic holm oak in Zafferana Etnea, Italy.

Ilice di Carrinu is a holm oak (Quercus ilex) at 937 m on volcanic ground in Etna Park, in the territory of Zafferana Etnea, surrounded by a hazelnut grove. At about 2.60 m the trunk divides into four large limbs supporting a globose crown roughly 30 m across and covering some 650 m². Wind-shaped branches spiral and touch the ground downhill, beside a ruined house of lava stone.

The holm oak is estimated to be over 700 years old, making it the oldest known holm oak on Etna. In 1982 the Corpo forestale dello Stato listed it among Italy's 22,000 trees of notable interest, singling it out as one of only 150 of exceptional historical or monumental value. It has survived lava flows that destroyed entire forests and centuries of weathering.

The name comes from Carlo, a former landowner whose local nickname Carrinu became permanently linked to this oak. Visitors today come simply to stand beneath its wide canopy and take in its scale.

The tree sits at around 940 meters (3,100 ft) elevation inside Etna Park and is reached by marked walking trails. Starting from the village of Milo, near Zafferana Etnea, is generally the most straightforward option.

The branches of this oak reach farther horizontally than those of any other documented specimen of its kind in Italy. This makes it a reference point for researchers who study monumental trees across the country.
