A very special category of sights in Greece are the castles and what remains of them over the years. Some more and some less known, each has written its own history..

One of the most impressive and not so well known fortresses in Greece is located in Agrinio.

The imposing and unknown acropolis of the area was a very important fortress with large fortifications and special features. Also known as Vlochos or Glas, this acropolis offers a unique view and a visit there is a unique experience.

The acropolis of Thestia overlooks the plain of Agrinio and in good weather you can see all the way to the Ionian Sea. In ancient times, the castle was the acropolis of the city of Thestia, founded by the mythical king Thestios. But later and especially during the Neolithic period, the walls were built, ie this important and extensive fortress.

Thestia was one of the city-states that flourished during the Mycenaean era until the Classical years. What distinguishes this acropolis in ancient Greece, but still today, is its impressive fortifications. Built at an altitude of 700 meters, its castle was also surrounded by strong walls that offer a unique view due to its location. Characteristic of the fortification of the Acropolis was that the perimeter of the walls reached 4,000 meters, surpassing even Agrinio. If you are at the site today, you will see that only one column similar to the Mycenaean one of Tiryns has survived.

Around 1450, the castle, which is one of the most important castles in Greece, was conquered by the Ottomans and that was the point where its decline began on all levels. However, its glory did not fade. It passed through different hands and even became a fortress of Ali Pasha. During the time of the Greek Revolution of 1821 , it became a base and shelter for warlords and military corps.

Seeing the castle today, you can take an imaginary journey through time and history. Below this acropolis today is the monastery of Panagia Vlohaitissa, where a school used to operate. Saint Cosmas of Aetolia also studied there.

Ruins of the ancient fortress can still be seen on the historic hill. One of the fortresses of Greece with an interesting history worth knowing.
