4. Messianic Castle of Patras
Located at the foot of mount Panachaikos, with its foundations dated at around 600 AD, during the reign of emperor of Constantinople (modern day Istanbul) Justinian. Its construction was carried out with building material of the ancient acropolis located at the same place that has already collapsed.
The history of the Castle is long and closely connected with the history of the city. In the 9th century Patras was attacked by the Slavs and Saracens from land and sea. The invaders were defeated and their defeat was attributed to the Patron Saint Andreas. In 1205 the Franks occupy the city and the Castle and Patras has been turned into a barony belonging to the Principate of Achaia based in Andravida. At the same time it became the seat of the Latin archbishop, which gradually acquired great political power. In 1408 the Pope leased the city to the Venetians for 5 years along with the castle as headquarters.
In 1428 the emperor of Constantinople, Constantine Paleologos liberated the Castle, the walls of which were repaired and additions were made. In 1458 the city was handed over to the Turks and gradually the Castle was transformed into an administrative center, as the military defense of the area was transferred to the Castle of Rio. Today, inside the Castle, elements of the Ancient Acropolis are preserved as its reconstruction was carried out with materials that pre-existed in the area.
