The medieval rock relief known as The Madara Horse Rider is located above the modern village of Madara, 15 km to the east of the city of Shumen. It is the only rock relief in Europe from the early medieval period, which is dated, according to the attendant inscriptions in Greek language, in the 8th century.
The Madara Horse Rider was documented and described for the first time in 1872 by the Hungarian explorer of the Bulgarian lands Felix Kanitz.
In 1979 the Madara Horse Rider was included in the UNESCO World Cultural Heritage List. The main challenges for the preservation of the rock relief are related to natural phenomena, such as acid rains, temperature amplitudes, wind erosion, etc.
