Answer: Kerala
Notes: The 'Arattu' festival has a rich tradition of being celebrated at the Sree Padmanabha Swamy Temple in Thiruvananthapuram. The uniqueness of the 'Arattu' festival is that the head of the royal family of the erstwhile Travancore kingdom still escorts the idols of deities during the procession in traditional attire. The Aarattu Festival is celebrated twice each year.
