The Dymaean Wall (Teichos Dymaiōn) or Kalogria Castle is a prehistoric acropolis in western Achaea, Greece. The fortress stands in a strategic position on a rocky hilltop, north of the Prokopos lagoon, near the village of Araxos. It was built in the Mycenaean period, probably around 1300 BC, but human occupation of the site started already around 3500 BC. It was deserted in the 18th century AD. During World War II it was used by occupying Italian forces, who built a number of military installations on the site and damaged the prehistoric fortifications.
It was named the Dymaean Wall after the nearby ancient city of Dyme. During the war between the Achaean and the Aetolian Leagues (220–217 BC) it was seized by king Philip V of Macedon.
References:The Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
