This is the best place I visited during my Kumbakonam Trip. This houses "Swetha Vinayagar Temple" that is very very auspicious and has a lot of spiritual significance. The deity is supposed to be lasting the past yugas..!
Thiruvalanchuzhi is a couple of Kilometers from Swamimalai that is about 6 KMs from Kumbakonam.
The temple is situated in a sprawling area..Has a number of imposing mandapams.
This is one of the best temples I ever visited.See for yourself...!
