 Originally, the Nellaiappar and Kanthimathi temples were two independent structures with spaces in between.It was in 1647 that Thiru Vadamalaiappa Pillaiyan, a great devotee of Siva linked the two temples by building the "Chain mandapam" (In Tamil Sangili Mandapam).In the centre of the Flower Garden is a square vasantha mandapam with 100 pillars.
