The most impressive and unique feature of the temple were the pillars, each one had a lion carved on it. They support the enclosed passage inside the temple. This architectural style, that of pillars in rows, led to a distinctive style followed by the later temples. It led to the evolution of the architectural style of 1000 pillared halls in later temples.
The walls too are carved depicting the stories of war scenes between the Pallavas and Chalukyas. One panel describes the history of the temple in eighth century script. The religious sculptures found on the inner walls of the verandah running around the four sides of this temple are very unique and important.
The information here is not found in any other temples of India. The numerous inscriptions of the Pallava dynasty of the Vaikuntha Perumal temple have helped the historians of South India to write about all the events of ancient Pallava history and to fix the chronology of this dynasty.
It would be wise to take the help of a guide here, I found them quite eager to explain and knowledgeable too.
