Construction of the temple pond

Perumthachan was once assigned to construct a temple pond. But it so happened that a dispute arose among three Karakkars (local residents) of the place about the shape of the pond, which was going to be constructed. One side wanted a rectangular pond, the second wanted a square pond, where as the third side the pond to be of a circular shape. Perumthachan agreed to construct a pond which would satisfy all the three demands. When the pond was constructed, the Karakkars from the three sides were happy to see their desired shape of the pond. It was so because the original shape of the pond was neither of these three but a highly irregular shape, which created an illusion .

The Shiva temple at Uliyannore and the Valluvanad temples that still exist in Kerala are attributed to Perumthachan.
