These are a set of 5 temples which are located in what were forests earlier. While not a very well known or popular group/circuit, these temples are revered by those at these five locations. “Kaa” refers to “kaadu” or forest. The five are: Tiruvanaikkaa, Tirunellikka, Tirukolakka, Tirukurakkaa and Tirukodikkaa. (These place names are often pronounced with a suffix “val” – as in Tiruvanaikkaval– which is considered incorrect.)
