Making such a big cave by cutting just 3 rocks is not an easy task. It is true that many people must have built this cave. If we look at it, the technology of so many years ago would be much higher than the current technology, that is why it became possible to do this kind of architecture. The way the design has been made in it is really a wonderful art work in itself and I appreciate this workmanship.
