The city was situated on a height 40 stadia from the sea, and southeast of Helike. Its name occurs in a line of Aeschylus, preserved by Strabo. It was swallowed up by the earthquake which destroyed Helike in 373 BCE, and all its inhabitants perished except those who were absent at the time. On their return they rebuilt the city, which was visited by Pausanias, who mentions its temples dedicated to Demeter, Aphrodite, Eileithyia and Isis. Strabo relates that there was a fountain at Boura called "Sybaris", from which the river and city in Magna Graecia, Italy derived its name. On the revival of the Achaean League in 280 BCE, Boura was governed by a tyrant, whom the inhabitants slew in 275 BCE, and then joined the confederacy. A little to the east of Boura was the river Buraïcus; and on the banks of this river, between Boura and the sea, was an oracular cavern of Heracles surnamed Buraicus.
The ruins of Boura have been discovered nearly midway between the rivers of Bokhusia (Cerynites), and of Kalavryta (Buraicus) near Trupia. Ovid says that the ruins of Boura (which he calls Bira), like those of Helike, were still to be seen at the bottom of the sea. Pliny the Elder makes the same assertion. Hence it has been supposed that the ancient Boura stood upon the coast, and after its destruction was rebuilt inland; but neither Pausanias nor Strabo states that the ancient city was on the coast, and their words render it improbable.
