 The Ananda Nilaya Vimanam is a three-tiered canopy.The first mention of "Vimana" is from the renovation work of the temple between the 12th and 13th century AD when a second wall was constructed around the sanctum sanctorum enclosing the first wall to support the weight of the vimana.The Pandyan king Jatavarman Sundara Pandyan gold-plated the roof and donated the gilded "Kalasam".
