A forgotten Greek city plan in Sicily

Casmenae was an ancient Greek colony founded by Syracuse in 643 BC on the Hyblaean Mountains of Sicily. Discovered by archaeologist Paolo Orsi in the 20th century, the city's unique feature is the evident warrior heritage, as hinted by various weapons found within the site. Among the excavated remains are four houses and a temple that already existed before the settlers' arrival - the latter has polychromatic ceramic decoration and, judging by the several weapons found in it, associated with a warrior god. However, Casmenae was abandoned during the 3rd century BC, and its walls, over 3 kilometers long, still remain. One of the most reliable sources for Casmenae is Thucydides and his History of the Peloponnesian War.
