In every village in Tamil Nadu, it is common to find a Shiva temple, a Vishnu temple and the gramadevata temple. There will be many other temples too, of course - dedicated to Ganesha, Muruga, and so on - some with historical significance and some that have just come up as a result of devotees' desire to see one in their neighbourhood.
So, when visiting a place, it is up to us to choose to go to 1, 2 all 3 main temples based on our family's belief system. For instance, if you go to Kumbakonam, you have the Kumbeshwara temple dedicated to Lord Shiva, and Chakrapani, Sarangapani, and Ramaswamy temples for Vishnu. Uppiliappan is normally our first destination as He is our family deity. In Srirangam, there is the Vishnu temple that cannot be missed and Thiruvanaikkaval Shiva temple nearby is equally famous.
