The palace of Sultan Bazbahadur and Roopmati are exquisite examples of the Islamic style of architecture. They have large courtyards. The palace of Roopmati was used as a check post in the times of an invasion. The tale of these two still resonates in the monuments of Mandu. Sultan Bazbahadur had gone to the dense woods near the Narmada River. Here he heard a sweet voice singing a divine song. When he reached the spot, he saw a beautiful maiden singing to the woods, the deer and the birds. He was mesmerized by her beauty and enchanted by her voice. When he asked her to become his wife she told him that until and unless the River Narmada starts flowing at Mandu she will not be able to marry him. This was because she used to pay homage to the river before having her food. The Sultan then went to the river and asked it to climb over the mountain and start flowing at Mandu. The river god granted his wish and told him to search for a sacred tamarisk and dig wherever it is found. There he found a spring of pure Narmada water which was a tributary. The king dug a reservoir at the place which was called the Rewa Kund. Rewa is another name of the river Narmada. He built a palace at this place and the waters of the fountain were provided to the baths of the palace. The river can be seen at a distance, as a silvery shimmering line in the Nimar plains, from the palace. Bazbahadur was later defeated in a battle and fled from the battle field. Roopmati committed suicide after consuming poison. The balladeers of Malwa still tell you their story.
