The cave of Neptune (Posseidon); at the site of Myloi, a monumental
chiselled structure believed to have been a tomb or a shrine, in what seems to have been a widely usual style in Eastern Aegean. Traces and indications suggest the existence of a wooden kiosk in front. This may have been a shrine dedicated to Venus, a goddess having enjoyed a wide popularity amongst the masses. There have been various statuettes of the goddess unearthed around Pigadia.
Most probably there has stood an open-air sanctuary to Venus at the cave of the Virgin, 2km farther, towards the region of Vathypotamos. This cave has suffered extensive corrosion, partly as a result of its intensive use by shepherds.
