Pandava Thoothar Perumal temple - Kanchi - rare temple with Sri Krishna in Viswaroopam (giant size)

Pandavathoothar Perumal Temple or Thirupadagam in Kanchipuram, Tamil Nadu, is  said to be one of three oldest temples in  this temple town; the other two being Ulagalantha Perumal Temple and Yathothkari Perumal Temple. Built by the Pallavas of the late 8th century AD, with later contributions from Medieval Cholas and Vijayanagar kings, it is a Divyadesam shrine 
glorified by the Azhwar saints of 6th–9th centuries AD. Here, Vishnu,  is worshipped as Pandava Thoothar Perumal 
and his consort is Lakshmi as Rukmini. Pada meaning  big 
and Agam meaning  residence; ''Thirupadagam'' implies that 
Sri  Vishnu resides here with his giant form. The temple follows  the Thenkalai  Sambrathayam  of Vaishnavite tradition and follows vaikanasa agama.

The legend of this temple has close links with  an episode in Mahabharata. The cousins Kauravas and Pandavas had  an eternal enmity over the rights to rule the kingdom. The foamer were greedy and evil minded people thoroughly misguided by their equally bad uncle Sahuni. Once Krishna was on a visit to Hasthinapura to meet Kauravas with a missive (message or in local language Toothu) from Pandavas. Duryodhana head of the Kouravas, being vicious as he was, in order to kill Krishna he had a huge pit dug, and  covered it with a carpet and a chair studded with gems. Besides, he had  wrestlers hidden in the pit to  finish  Krishna.  Krishna, being an  avatar of Vishnu took  
Vishvarupa - a giant form in the court. Dhritarashtra, blind father of Duryodhana was just overwhelmed and requested Krishna to make him blind again as he did not wish  to see anything after this  Vishwaroopa Darshanam.  Janamajeya, the great-grandson of Arjuna was blessed with Vishwaroopa Darshanam in the later

The temple has three inscriptions on its walls, two dating from the period of Kulothunga Chola I (1070–1120 CE) and one to that of Rajadhiraja Chola (1018-54 CE). The inscriptions  on the  western wall of the central shrine from the period of Rajadhiraja Chola II (1166-78 CE)  mention  about gifts of 32 cows for lighting lamps of the temple.Close to the Ekambareswarar Temple, he main entrance of the temple faces east.   The temple  with a rectangular plan has a four-tiered rajagopuram and a single precinct enclosed in the walls. The Maha mandapa is believed to have been built by the Cholas, whereas the adjacent hall, it is believed,  was built during Vijayanagara Empire. The sanctum has a huge image of the deity - Pandava Thoothar,  25 ft (7.6 m).tall.  Believe it or not such a giant image of  Sri Krishna  consecrated about 1000 years ago  is one of its kind in India, The Sri Krishna  is seen seated in Arda Padmasana posture with his right leg bent to the basement.  He  appeared as a human, hnce  there are only two hands to the deity,
