On the crest of the eastern glacis of the citadel is the Asar Mahal which of all the Royal palaces, has alone escaped destruction. It was built by Sultan Mahmud in about 1646, and it was intended to serve the purpose of a Hall of Justice and it was originally called Adalat Mahal. To make it accessible from the royal residence, a covered passage was carried on piers across the moat to connect it with the citadel. The walls and ceilings of the rooms of the south side of the gilded hall is a gorgeously painted apartment.
Aurangazeb, it is said, was incensed on seeing the human figures painted on the walls, and ordered the faces of all the figures whitewashed. Of late, they have been attempted to be restored. On the ground floor, at· the foot of the southern staircase is a closed room which was the Kitabkhana or library. Out, in the front of the building is a great square tank still fed by the Begum Talaze and Toravi conduits. On the edge of this pond, near the southern entrance are some wonderfully large slabs of green stone and slate, and in the front verandah is a beautiful oblong slab of shell marble said to have been brought from Arabia.
