A few years ago petrified wood was discovered near the village of Sigri. Excavations started and a complete forest was discovered. More and more sites have been discovered since that time and so all the island of Lesbos is protected as an UNESCO geoparc. The fossile forest was preserved by the ash of volcanic eruptions that took place 23 million years ago. The volcanic centers of these eruptions can still be seen on the island.

Also outside the excavations there are many places, where you could find fossile wood, but please not that it is not permitted to keep it! All the island is a strictly protected geoparc by UNESCO.
