The Madara Rider or Madara Horseman is a large early medieval rock relief carved on the Madara Plateau east of Shumen. The monument is dated to the very late 7th or more often the very early 8th century, during the reign of the Bulgar Khan Tervel. In 1979, the monument was listed as a UNESCO World Heritage Site.
The relief sculpture depicts a majestic horseman, approximately 23 m above ground level, carved into an almost vertical 100 m-high cliff. The sculpture is almost life-size. The horseman, facing right, is thrusting a spear into a lion lying at his horse's feet, and on the left a dog is running after the horseman. The carving of the horseman's halo and garments, as well as the bird in front of the horseman's face, are barely recognizable due to centuries of erosion and the generally poor condition of the monument.
Three partially preserved texts in Medieval Greek, carved in the rock, can be found around the image of the rider. They bear important information regarding the history of Bulgaria in the period. The oldest inscription is the work of Tervel (701–718 AD), thus it is considered that the relief was created during his rule or immediately after the Bulgars settled the region in 680–681 AD. The other inscriptions refer to the Khans Krum (802–814 AD) and Omurtag (814–831 AD), who are most likely the ones who ordered the carvings.
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.
