उत्तर
In Vijaypur, Karnataka, there is an ancient site called Golghumat. The inside of its big circle is smooth and round, with a cap on top of it. Since the structure is circular, sound waves that start at one point are mirrored many times before going back to the same point, where they are heard more than once.
