Megalovouni mountain is 1,273 metres high, right on the border between Corinthia and Argolida regions, southeast of Nemea and the plains of Asopos. The rock of Polyfeggos is on the north, with the ruins of a Byzantine castle-city and a monastery of Panagia, and on the south is the mountain Farmakas.
On Megalovouni’s foot, in many places, are well-preserved parts of the underground Roman aqueduct made by Emperor Hadrian, that was in use up to the 4th century AD.
The relatively low altitude of Megalovouni makes most of its parts easily accessible, something that allowed for easy communication between the two areas of Corinthia and Argolida, even from the antiquity. The mountain is also known for its caves, such as those in the areas Gymno and Malantreni, named “Katafygia” (shelters), “Panagoulia” and “Fournos” (oven).
On an altitude of 780 metres, on the south-eastern slopes of the mountain, the settlement of Vilia was built, and higher up wind farms and telecommunications antennas can be found. Today, because of the problems caused by human actions and illegal hunting, the authorities have taken actions to prevent them and the altering of the natural environment they cause.
