Musical pillars
One thing that surprised me beyond measure and displayed the ingenuity of Vijayanagar Empire is the musical pillars. Small length pillars of 4 are built and arranged in such a manner to produce different music - not only of instruments, but even that of horse and so on. The guide informed us that when all the pillars where functioning, the music could be heard up to a kilometre!
