On a hill in Mesopotamos village, 48 km away from Preveza, there is the oldest Nekromantheio of Acheron, near the ancient Mycenaean colony of Efyra (14th 13th century BC). This is the place where the gates of the Lower World existed, the entrance to the kingdom of Hades. According to the legend, Hermes led the souls to Hades and people from all over the world used to come in order to communicate with the souls of their beloved people.
The area where Nekromantio is located is easily accessible via the existing road network and within a walking distance of Vrachos, Ammoudia, Lygia, Loutsa etc. It is definitely worth visiting!
