Larissos (river)

The Larissos was a small river in ancient Greece, located in the region of Achaea. It served as the border between Achaea and Elis. It flowed into the Ionian Sea. While not a major river in terms of length or navigability, its significance lay in its role as a boundary marker between two important regions of the Peloponnese. Sources from antiquity mention the Larissos in connection with accounts of territorial disputes and political geography.
