Natural History Museum of the Lesvos Petrified Forest, Geological museum in Sigri, Lesbos, Greece.

The Natural History Museum of the Lesvos Petrified Forest sits in Sigri and displays fossilized tree trunks and plant remains from millions of years ago. The collections show how ancient forests were buried and preserved by volcanic activity, creating a record of Earth's past environments.

The fossils here date from the Miocene epoch, when the region was covered in subtropical forests that later turned to stone. Established in 1994, the museum became an important center for understanding this distant geological period and its environmental conditions.

The museum's permanent exhibition, "The Geohistorical Evolution of the Aegean", traces the formation of the Aegean Sea, the island's volcanoes and its first human inhabitants through models and finds. A small mineral collection holds quartz, amethyst and chalcedony specimens from the area.

The museum is located in Sigri on the western side of the island and is easy to reach on foot. Plan enough time to walk through each room at your own pace, since the details and displays help you fully understand the geological story.

The museum uses drones with 4K video and augmented reality to map excavations of petrified trunks. A mobile app lets visitors see 3D models of the digs and compare different excavation periods. In 2021 the museum received a bronze prize from the Boussias organisation for promoting and conserving the Petrified Forest.
