Gonnus

It stood on the northern side of the Peneius, near the entrance of the only two passes by which an enemy can penetrate into Thessaly from the north.

On this occasion Livy says that Gonnus was 20 miles (32 km) from Larissa, and describes it as situated "in ipsis faucibus saltus quæ Tempe appellantur.

"[7] In 171 BCE it was strongly fortified by Perseus of Macedon; and when this monarch retired into Macedonia, the Roman consul Licinius advanced against the town, but found it impregnable.

[9][10] The editors of the Barrington Atlas of the Greek and Roman World locate Gonnus at the modern town of Gonnoi.

[11] A site, called Gonoussa (Γονούσσα), about 2 kilometres (1.2 mi) southeast of the modern town has been excavated extensively.
