The Thracian Tomb of Svestari is 2.5 kilometers southwest of the village of Sveshtari in northeast Bulgaria. The tomb is probably the grave of Dromichaetes (c. 300 – c. 280 BCE) who was a king of the Getae on both sides of the lower Danube (present day Romania and Bulgaria) around 300 BCE, and his wife, the daughter of King Lysimachus who was a general and diadochus (i.e. 'successor') of Alexander the Great. The tomb is a UNESCO World Heritage Site.
Sveshtari tomb was built in the first quarter of the 3rd century BC and discovered in 1982. It reflects the fundamental structural principles of Thracian cult buildings. The tomb has a unique architectural decor, with polychrome half-human, half-plant caryatids and painted murals. The 10 female figures carved in high relief on the walls of the central chamber and the decoration of the lunette in its vault are the only examples of this type found so far in the Thracian lands. It is a remarkable reminder of the culture of the Getes, a Thracian people who were in contact with the Hellenistic and Hyperborean worlds, according to ancient geographers.
In 2012, archaeologists uncovered a significant treasure near the village. The treasure included a golden ring, 44 female figure depictions and 100 golden buttons, found in 150 tombs from the 4th century BC. It has been suggested that it is part of the site of the Getan city of Helis.
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.
