Not Fort Agra, but near Agra.
This imposing palace comprising the principal haramsara of Akbar has been wrongly ascribed to Jodh Bai who has nothing to do with Sikri. It is the most impressive of all the royal edifices. It consists of a large open quadrangle on the sides of which are suites of single-stories rooms with double stories blocks in the center and corners to break the sky-line. The Central block on the east forms a vestibule to the main entrance of the building and on the west is a small shrine supported on richly carved pillars. The shrine has niches for keeping images of Hindu deities and a platform for the principal deity. The Azure-blue glazed tiles of the rood of this palace are also noteworthy. It was most probably build between A.D 1570 and 1574.

Though “Miriam’s House” is generally regarded as the abode of Mariam Zâmâni, there is a great deal to support the view that the spacious palace known as Jodh Bai’s Mahal, or Jahangiri Mahal, was really her residence. It is undoubtedly one of the oldest buildings in Fatehpur.
We know that Akbar went there on Mariam’s account; and, after Jahangir’s birth, Akbar’s first care would be to build a palace for the mother and her child, his long-wished-for heir. Mariam was a Hindu, and this palace in all its construction and nearly all its ornamentation belongs to the Hindu and Jaina styles of Mariam’s native country, Rajputana. It even contains a Hindu temple. It is also the most important of all the palaces, and Mariam, as mother of the heir-apparent, would take precedence of all the other wives.
On the left of the entrance is a small guard-house. A simple but finely proportioned gateway leads through a vestibule into the inner quadrangle. The style of the whole palace is much less ornate than the other zanana buildings, but it is always dignified and in excellent taste. It must be remembered that the severity of the architectural design was relieved by bright colouring and rich purdahs, which were used to secure privacy for the ladies of the zanana and to diminish the glare of the sunlight.
