Teichos Dymaion Fortress 🏰 Kalogria (1300 BC)
Highlight • Historical Site
In historical times human activity at Teichos Dymaion was, more or less, continuous. During the war between the Achaean and the Aitolian Leagues (220-217 BC) the site was seized by the Aitolian general Eutichidas and was later taken without battle by king Philip V of Macedonia, who subsequently handed it to the Dymaians. In roman times the acropolis was part of the Colonia Iulia Augusta Dumaeorum (the imperial colony of Dyme) and was probably inhabited by roman settlers.
Intensive use of the site continued during the byzantine era. Significant alterations to the citadel’s original form took place during the middle byzantine period (10th-12th c AD): a cross wall, dividing the acropolis in two parts, was built at that time, along with a tower over the southeastern corner of the fortification; the middle gate was disused and blocked by a wall.
The Venetians took over the acropolis in 1408, the catholic bishop of Patra leased the barony of Patra to them for five years. Later on (1687-1715), 1000 settlers from Lidhoriki central Greece came to live in the surrounding area that was then uninhabited; this is probably the period during which the northern part of the acropolis was used as a cemetery. After that, habitation on the site was very sporadic and has left no traces. When a number of western European travelers visited Teichos Dymaion during the 19th it was found deserted.
Dring World War II, the site was used as a military camp by the Italian occupation troops, causing irreversible damages.

The ruins of Teichos Dymaion (also known as the "Dymaean Walls" or Kastro tis Kalogrias) are a significant archaeological site in the Achaia prefecture of Greece. The main fortress was built during the Mycenaean period, around 1300 BC. It is the only fortified Mycenaean acropolis in western Greece. Cyclopean Walls: The fortifications were constructed using the so-called "cyclopean" style, with massive limestone blocks. The walls were originally about 200-250 meters long, up to 10 meters high, and about 5 meters thick. The site was almost continuously inhabited for about 5,500 years, from the Neolithic period (around 3500 BC) until the Venetian period in the 18th century. According to legend, the Wall of Heracles was built during his war against the Eleans under King Augeas.

Within the fortress grounds are the remains of an Ottoman hammam (Turkish bath). These baths are a fascinating testament to the Ottoman presence in the region. Typical features of these baths are the small, stone vaults and the characteristic skylights in the ceilings, through which daylight once filtered into the steam-filled rooms. They served not only for hygiene but were also important social gathering places within the garrison. Today, they survive as ruins, which can be visited during a tour of the extensive complex. They are often somewhat hidden between the massive fortress walls and the Venetian additions.

High above the city lies the ancient acropolis. This imposing structure, dating from the Turkish and Venetian periods, offers a stunning view of the Angel Islands and the surrounding mountain ranges. Particularly noteworthy are the massive tower on the west side and the bastion at the northeast corner.

The entrance fee has increased to €5 (2025). Since there are no tickets and no price list, I doubt that this is an official charge. A visit is worthwhile in any case.
