Thanjavur Big temple is made of a rock and is rocking always.Its architectural beauty is a mind-blowing one.The Kalasa(the topmost part of the temple) is made up of a single stone and it has a weight of about some Tons.In those years there is no cranes or any other facilities but somehow it is arranged.I am very much surprised after knowing this fact.In addition this temple shreds no shadow of its tower anywhere on the ground even due to Sun's exposure everywhere around it.This is really a great piece of art adding credits to Tamil Nadu and Thanjavur.
