The Venetian fortifications of Mt. Oneia are among the fortified positions of Corinthia. They lie 8 km south of Corinth.
What to expect
Whoever held Corinthia held the way into the Peloponnese, so the region filled with small castles and towers at every critical point. Most survive as ruins standing in open country.
