To the west of the Dionysos theatre and quite close to the cliff of the Acropolis lies the Asklepieion, the sanctuary of the healing god Asklepios dated to 420 BC. Functioning pretty much as hospitals, the asklepieia were of immense importance in ancient Greece, the most popular being the Asklepieion of Epidaurus. Besides the usual facilities for sheltering the pilgrims, the core structures of the Athenian complex were the temple of the god and the enkoimeterion (dormitory). That was a large two-storey stoa for the enkoimesis of the patients, a dream-like and rather hallucinatory state of sleep induction, practised in those shrines. While in hypnotic state, the patients waited to receive a dream vision of the god who would either give medical advice or even miraculously cure them. Votive offerings that came to light from the site often depict healed body parts. Characteristic examples are on display in the Acropolis Museum.
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.
