Dolmen circle is also one of the must-see attractions in Kodai and is situated just very close to ParvathaVihar and the Pannikadu. Dolmens and Kistavens were used as burial grounds. Dolmens are usually made up of two very big and straight stone slabs topped by a flat slab of stone just like a roof. It is quite amazing to view Dolmens and Kistavens of the pre-historic period of 5000BC. So, if making plan to visit Kodai, then sure add this attraction to your list for visiting.
