Beautiful frescos on the walls of the Tanjore Big Temple.
The frescos on the walls of the Tanjore (Thanjavur) Big Temple are some of the most beautiful, intricate and richest ancient paintings that i've ever seen in my life. These paintings tell stories of the origins of the temple itself and of its patrons (mainly Raja Raja Cholan). Created using plant extracts and other natural preservatives, these paintings remain vibrant and rich even today, some 1000 years later, but not much could be said about the state of the plaster and the walls over which they are painted upon.
Many of these paintings can be found along the outer corridors of the temple, while its Gopuram is said to contain even more beautiful and delicate works.
