コリントス地峡
The Corinth Canal, carrying ship traffic between the Ionian and the Aegean seas, is about 4 km east of Corinth, cutting through the Isthmus of Corinth. Corinthia is increasingly seen as part of the wider metropolitan area of Athens, with municipalities, such as Agioi Theodoroi in the easternmost part of the regional unit, being considered suburbs of Athens.
