Gonnus

Gonnus (Γόννοι) was an ancient Greek polis of the Perrhaebi in Thessaly, situated on the northern bank of the Peneius River at the narrow entrance to the Vale of Tempe[1]. Its strategic position at one of only two northern passes into Thessaly made it a key defensive stronghold, controlling access to the region from Macedonia[1]. According to later Greek critics, the settlement was named after Gonneus, a figure mentioned in Homer's Iliad[1]. The pass west of Tempe leading through Mount Olympus into Thessaly was used by Xerxes I's army during the Persian invasion of 480 BC[1].
