A rare geological phenomenon, the so-called “Dolines” at the village of Didyma.

Sinkholes at Didyma

A few kilometers from the picturesque village of Didyma in Ermionida is a rare geological phenomenon—two strange and imposing craters created by natural processes of erosion, forming large sinkholes or "dolines."

The large doline forms a natural amphitheater, which was inhabited since the prehistoric age, as evidenced by the stone tools that the excavation brought to light. The smaller doline presents a great interest due to the numerous erosions marked on the ground. Two small byzantine churches are built under the cliff, surrounded by an abundance of wild vegetation; the church of Saint George with its 13th century murals and the church of Jesus Transfiguration.

Access to the interior of the cave is possible through a cavity dug in the ground and a carved staircase leading to the rock.
