The Ancient Thracian shrine of Beglik Tash near the Bulgarian Black Sea resort of Primorsko is located on the plateau with the same name, which also harbors the Ancient Thracian city Ranuli. The Beglik Tash Shrine has been explored by Bulgarian archaeologists have explored since 2002. Archaeologist Prof. Nikolay Ovcharov has discovered there a second “womb-case” located under the Lion’s Head hill, after having found one in the Eastern Rhodope Mountains. The cave goes down to a depth of five meters. Inside, Ovcharov has found ceramics from the Early Iron Age (10th-6th century BC), the Antiquity, and the Middle Ages, as well as a man-made stone altar at the end of the natural cave which proves that it was used as a shrine. Every day at noon, a ray of sunlight enters the narrow entrance of the cave, and projects itself on the back of cave. This is precisely the concept of the Ancient Thracian womb-caves described by late Bulgarian archaeologist Prof. Alexander Fol, the founder of thracology, the study of Ancient Thrace. Fol hypothesized that some caves in Bulgaria where the sunlight entered only at certain times of the day where seen by the Thracians as acts of symbolic fertilization of the Earth womb or the Mother Goddess by the sun phallus of the Sun God creating fertility.
In the vicinity of the cave under the Lion’s Head hill at Beglik Tash archaeologist Tsonya Drazheva has discovered over 15 dolmens from the Early Iron Age (10th-6th century BC) as well as the famous megalithic shrine of Beglik Tash where she has found two giant stone circles created humans.
