It is a megalithic sanctuary, carved into the limestone mass, which dates back to 4000 BC, and possibly even earlier.
The underground structure has 34 rooms and an area of 480 square meters. In addition, many objects in the building have been polished and given the correct shape.
Historians believe that in ancient times, 6-7 thousand people could have been buried in the structure. However, for unknown reasons, the remains were never found.
The only thing worth saying is that human remains were found together with animal remains, and they were all scattered. It is likely that all of this was used for rituals and sacrifices.
What conclusions can be drawn? Although it is not as difficult to gouge the complex in limestone as in granite, the dimensions are still quite large, especially when considering the age of 6,000 years or even more.

It is believed that the sanctuary was built by the same civilization as the temples on the surface. Just what kind of civilization was it and what technologies did it have?
