Stratos (Greek: Στράτος, Latin: Stratus) is a settlement in central Aetolia-Acarnania, Western Greece.

It is best known for its remains of the namesake ancient Greek city and capital of Acarnania, which lie on a hillside about 500m north of the modern village.

[2] Its situation at the northern edge of the fertile Achelous River plain and on the strategic maritime route to Italy as well as the navigability of the river up to city[3] made it a place of great military importance [4] and Stratos emerged as the largest and best fortified city of Acarnania.

It was where judicial proceedings common to all the Arcananians took place,[5] and by Thucydides' time Stratos was the capital of Acarnania and the federal assemblies were held there.

The remains of the temple show the exquisite detail of sculpture in its construction, and also the excellent state of preservation of the base and many constituent blocks despite almost 2500 years of weathering.

The area enclosed by the city walls of 7.5 km length including four long hills and three valleys is alone impressive, their height and strength also.
