Temple exterior - Outer parapet wall of the Mantapa

The outer parapet wall of the open mantapa has a total of 140-panel sculptures with depictions from the Hindu epics. The Ramayana is sculpted on the south side wall on 70 panels, with the story proceeding quite unusually, in an anti-clockwise direction.

You can see them here Temples of Karnataka.

Quoting from the above website,

"The story (of Ramayana) is divided into seven main kandas as per Valmiki (Bala, Ayodhya, Aranya, Khiskinda, Sundara , Yuddha and Uttara Kanda. In this temple (at Amruthapura) Uttara Kanda is missing."

The entire Ramayana can be seen unfolding on the walls of Amriteshwara temple. The story begins from when King Dasharatha performs a fire sacrifice called the Putrakameshti Yaga. The final relief is of Lord Rama defeating Ravana to reunite with Seeta.
