Zakros contains ruins from the Minoan civilization. The site is often known to archaeologists as Zakro or Kato Zakro. It is believed to have been one of the four main administrative centers of the Minoans, and its protected harbor and strategic location made it an important commercial hub for trade to the east.
The town was dominated by the Palace of Zakro, originally built around 1900 BC, rebuilt around 1600 BC, and destroyed around 1450 BC along with the other major centers of Minoan civilization. Extensive ruins of the palace remain, and are a popular tourist destination.
A ravine known as the 'Ravine of the Dead' runs through both the upper and lower parts of the ancient site, named after the numerous burials that have been found in the caves along its walls.
Zakro was first excavated by D.G. Hogarth of the British School of Archaeology at Athens and 12 houses were unearthed before the site was abandoned. In 1961, Nikolaos Platon resumed the excavation and discovered the Palace of Zakro. This site has yielded several clay tablets with Linear A inscriptions.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
