Asopos (Boeotia)

The Asopos (referred to in Latin sources as Asopus) is a river in Boeotia and northern Attica, Greece. In antiquity, it formed the border between the cities of Thebes and Plataea. The Battle of Plataea was fought on its banks. According to Pausanias (5.14.3) the Boeotian Asopus can produce the tallest reeds of any river. Its source is on the northern slope of the Cithaeron mountain, southwest of Thebes. It empties into the South Euboean Gulf, near Skala Oropou. Its total length is 57 km. Its basin is 718 km2. The Asopos flows along the following places, from the source downstream: Lefktra, Agios Thomas, Oinofyta, Sykamino, Skala Oropou. The river is polluted with hexavalent chromium due to industrial activity.
