Padmanabhaswamy Temple is located in Thiruvananthapuram, Kerala, India. The temple is built in an intricate fusion of the indigenous Kerala style and the Tamil style (kovil) of architecture associated with the temples located in the neighbouring state of Tamil Nadu, featuring high walls, and a 16th-century Gopuram. While the Moolasthanam of the temple is the Ananthapuram Temple in Kumbala in Kasargod District, architecturally to some extent, the temple is a replica of the Adikesava Perumal temple located in Thiruvattar, Kanyakumari District.
The Supreme Principal Deity Para brahman, Maha Vishnu/Adi Narayana is enshrined in the "Anantha Shayanam" posture, the eternal yogic sleep on the serpent Adisheshan. Sree Padmanabhaswamy is the tutelary deity of the royal family of Travancore. The titular Maharaja of Travancore Moolam Thirunal Rama Varma is the trustee of the temple. In line with the Temple Entry Proclamation, only those who profess the Hindu faith are permitted entry to the temple and devotees have to strictly follow the dress code. The name of the city of Thiruvananthapuram in Malayalam translates to "The City of Lord Ananta", referring to the deity of Padmanabhaswamy Temple.
