It is also said that a saint of 12th century was searching for a place to settle down. His master gave him a small dry twig and asked him to settle in the place where the twig comes back to life and blooms. He travelled to many places and at last came to this fort. He planted the twig under a tree and slept. He woke up and saw the twig bloomed into a small plant.
