According to book references, the ancient town Amphidolis was located at the site of present Karatoula.. Ottoman Years: Karatoula was the largest village of Oleni region and almost at the center of many other small villages, at the time. It had an "Agas" administrative seat. The name of its first Agas was Kara-Toulas, hence the name of the village changed to Karatoula. Agas built his residence palace in the eastern part of the village on the dominant hill, the ruins of which survive even today, next to house Theodore Theodorakopoulos, doctor.

Karatoula as adjoining the Episkopin Olena, and as relations with their respective bishops, had a high influence on all the passages of Oleni. In the northern part of the village and spaced about twenty minutes there was small underground church. Ruins are preserved today under the name "Agios Dimitrios".

Karatoula gave brave warriors under the leadership of Pierros and Davouras, who met with other soldiers rising for Poussi Greek troops and took part in the battle Bodine.
