A giardino pantesco is a circular stone wall, three to five metres high, built around a single fruit tree to shelter it from the salt-laden wind and to collect dew off the porous lava. They are found nowhere else on earth and are one of the most beautiful examples of agricultural adaptation in the Mediterranean.
The best-preserved example, restored by FAI (the Italian National Trust), is on the road between Khamma and Tracino. The garden encloses an orange tree planted in volcanic soil and is open to the public; the entrance fee includes a short guided explanation of how the walls work hydrologically and why the form has not changed in centuries.
