Adi Sankara's Keerthisthambam (pillar of fame) in Kalady is a large open structure on the banks of the River Periyar. On the top of the multi-storey structure built as a monument for Adi Sankara by Kanchu Mutt, a lively statue of Adi Sankara is adorned. One can climb up to the top to get a full view of the statue.

There are many inscriptions describing the episodes from the life and mission of Adi Sankara on the walls surrounding the image. One can get the bird’s eye view of the surrounding natural landscapes from this top of the Keerthisthambam.
