Aranmula Parthasarathy Temple

The temple tank called "Thiruallikeni" is derived from the place where Vishnu's consort Lakshmi herself was born as Vedavalli to Sage Bhrigu. The tank contains five wells and lies opposite to the eastern entrance of the temple.

The temple has two main shrines built back-to-back. The Mulavar (main deity), Parthasarathy alias Venkata Krishnan, faces East. Along with his consort Rukmani Piratiyar, he holds sword in one hand, Varadha Muthirai on the other hand. Krishna's brother Balarama is positioned on his right, Satyaki to his left; Krishna's son Pradyumna and grandson Aniruddha are also found in the sanctum. This is one of the Vishnu temples where the Vishnu is present along with his three generations. The shrine of the consort, Vedavalli Thayaar, is located parallel to the sanctum. The shrine of Narasimha (Thellia Singhar) faces west and just as the main sanctum, there is a separate entrance and flag post (Dwajasthambam) for Narasimha. The deity is seated in Veetrirundha Yoga thirukola (Sitting Posture).

There is a shrine for Ranganatha (Sri Mannanathar) and Ramar located in the passage to the main sanctum. Ranganatha is in Bujanga Sayanam, reclining posture facing east. There is a shrine of Gajendra Varadar There is a shrine for Rama (an avatar of Vishnu), known here as Chakravarthi Thirumagan. He is seen here with his entire family, ie, consort Sita Piratti, brothers Lakshmana, Bharatha,shathrugna and devotee Hanuman opposite to Rama shrine.

It is one of the very few shrines in the country dedicated to Krishna as Parthasarathy, charioteer of Arjuna and to contains idols of three avatars of Vishnu: Narasimha, Rama, and Krishna. Because of the association of the temple with Krishna, Tiruvallikeni came to be regarded as the Southern Brindavana.
