Acrocorinth ancient fortress, Pelopponese, Greece 2000
Acrocorinth is a castle nestled on the steep rock of Acrocorinth and rising above the southwest of Ancient Corinth.
Acrocorinth (Greek: Ακροκόρινθος, lit. 'Upper Corinth' or 'the acropolis of ancient Corinth') is a monolithic rock overlooking the ancient city of Corinth, Greece. In the estimation of George Forrest, "It is the most impressive of the acropolis of mainland Greece."
The city's archaic acropolis was already an easily defensible position due to its geomorphology; it was further heavily fortified during the Byzantine Empire as it became the seat of the strategos of the thema of Hellas and later of the Peloponnese. It was defended against the Crusaders for three years by Leo Sgouros. Afterwards it became a fortress of the Frankish Principality of Achaea, the Venetians, and the Ottoman Turks.
With its secure water supply, Acrocorinth's fortress was repeatedly used as a last line of defense in southern Greece because it commanded the Isthmus of Corinth, repelling foes from entry by land into the Peloponnese peninsula.
