The Archaeological Museum of Nafplio has exhibits of the Neolithic, Chalcolithic, Helladic, Mycenaean, Classical, Hellenistic and Roman periods from all over southern Argolis.
A two-storey building constructed during the second period of the Venetian rule (1713) and converted into a museum in 1926, houses the collection of the Archaeological Museum in the historic district of Nafplion. The new permanent exhibition outlines the cultural identity of Argolida from the Paleolithic period until Roman times. The most important exhibits are associated with the Mycenaean centers of the region and present in detail the palatial system, as well as the daily life and burial customs of the Mycenaean world. On the first floor, a bronze armor from Dendra, found in a chamber tomb of the 15th century BC that belonged to a distinguished warrior, is the most remarkable object on display.
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.
