Saptha Stanam
The decorated palanquin used during the festival
The sapthasthanam festival is conducted at Tiruvaiyaru during April every year. As per Hindu legend, it is the wedding festival of Nandikeswara, the sacred bull of Shiva on the Punarpoosa star during the Tamil month of Panguni.
The festival deity of Aiyarappar temple of Thiruvaiyaru is carried in a decorated glass palanquin along with the images of Nandikeswara and Suyasayambikai to the temples in Thirupazhanam, Thiruchottruthurai, Thiruvedhikudi, Thirukandiyur and Thirupoonthurthi.
