It is in this temple that one notices for the first time two "gopuras" (gateway towers, here oriented in the same direction). They are architecturally coeval with the main vimana and are referred to in inscriptions as "Rajarajan tiruvasal" and "Keralantakan tiruvasal". In spite of the massive size of the "gopuras", the "vimana", rising majestically to a height of 190 feet, continues to dominate and it is only in the subsequent period that a change in the gradation of magnitude takes place.
