Kamarina

Founded in a marsh by Syrakousai in 599 BCE, Kamarina would later be destroyed by its founders before being rebuilt a century later by Olympic champion charioteer Psaumis. After an outbreak of disease, Kamarina would later drain its northern marshes in an attempt to ward off the illness despite an oracle's advice to the contrary; Carthage would take advantage of the lack of natural barriers and invade through the newly-created plains, destroying the city a second time.
