Eurymenae or Eurymenai (Greek, Ancient (to 1453);: Εὐρυμεναί or Εὐρυμέναι) or Erymnae or Erymnai (Ὲρυμναί) was a town and polis (city-state)[1] in Magnesia, ancient Thessaly, situated upon the Aegean Sea coast at the foot of Mount Ossa, between Rhizus and Myrae.[2] Pliny the Elder relates that crowns thrown into a fountain at Eurymenae became stones. It was destroyed by Lyciscus in the 4th century BCE.
The site has been located at a place called Kokkino Nero.
