Not to confuse this with the Octagonal Water pavilion you may find on the main road to Hampi. This structure, as the name indicates, is a gigantic bathing area made in the shape of an Octagon. The bath shelter is designed with an octagonal shaped platform at the middle and an encircling pillared veranda around it. The circular section between the veranda and the platform is the water (now empty) area. To the west of it you can spot the ruined bases of numerous palaces.
