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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
