Shrine of Acheloos, Pan and the Nymphs
From Project Athinai
A shrine dedicated to Acheloos, Pan and the Nymphs is mentioned by Plato who locates it in the district of Agrai on the eastern bank of the Ilissos in a beautiful area at the foot of the Ardettos hill, planted with great plane trees in the vicinity of a spring.
This shrine must not be confused with the Shrine of Pan and the Nymphs located further south on the east bank of the Ilissos against an artificial scarp.
The area was totally transformed when Lykourgos built a stadium on the same spot in 330 BC.
