"Waiting Hall"), also known as Nakkar Khana (drum house). Music was played daily, at scheduled times and everyone, except royalty, were required to dismount. Later Mughal kings Jahandar Shah (1712–13) and Farrukhsiyar (1713–19) are said to have been murdered here. The Indian War Memorial Museum is located on the second floor. The vaulted arcade of the Chhatta Chowk ends in the centre of the outer court, which measured . The side arcades and central tank were demolished after the 1857 rebellion. Diwan-i-Aam The inner main court to which the Nakkar Khana led was wide and deep, surrounded by guarded galleries. On the far side is the Diwan-i-Aam, the Public Audience Hall. This was a place for the official affairs of commoners who sought after legal matters such as tax issues, hereditary complications, and awqaf. The hall's columns and engrailed arches exhibit fine craftsmanship, and the hall was originally decorated with white chunam stucco. In the back in the raised recess the emperor gave his audience in the marble balcony (jharokha). The Diwan-i-Aam was also used for state functions. The courtyard (mardana) behind it leads to the imperial apartments. Mumtaz Mahal The two southernmost pavilions of the palace are zenanas (women's quarters), consisting of the Mumtaz Mahal built for Arjumand Banu Begum (Mumtaz Mahal) wife of the Mughal emperor Shah Jahan and the larger Rang Mahal a resort for royal women. The Mumtaz Mahal houses the Red Fort Archaeological Museum. Rang Mahal The Rang Mahal housed the emperor's wives and mistresses. Its name means "Palace of Colours", since it was brightly painted and decorated with a mosaic of mirrors. The central marble pool is fed by the Nahr-i-Bihisht ("River of Paradise"). Khas Mahal The Khas Mahal was the emperor's apartment. It was cooled by the Nahr-i-Bihisht. Connected to it is the Muthamman Burj, an octagonal tower where he appeared before the people waiting on the riverbank. This was done by most kings at the time. Diwan-i-Khas The Diwan-i-Khas (Hall of Private Audience) was a building for the official affairs and requests of the novelty and royal family. A gate on the north side of the Diwan-i-Aam leads to the innermost court of the palace (Jalau Khana) and the Diwan-i-Khas. It is constructed of white marble, inlaid with precious stones. The once-silver ceiling has been restored in wood. François Bernier described seeing the jewelled Peacock Throne here during the 17th century. At
