According to Homer, Kamena Vourla and Kenourgio are built on the site of the ancient town Thronio, while Renginio is built on the site of ancient Tarfi (native town of the Locrean hero, Aeas).

Present day towns have been built near the streams of the Voagrios River, as was also the case in ancient years. The healing water of the hot springs which contributes to the development of Kamena Vourla comes from the heart of Knimida, which lies very close to the bath town.
