Akbar's fort was positioned by the River Jamna, as though it were a garden. The two ladies palaces (zenana) called the Jahangiri Mahal and Akbari Mahal have paved internal courts rather than planted gardens. The Jahangiri Mahal has a a water channel connecting with an octagonal pool. The Anguri Bagh was rebuilt by Shah Jahan by 1637 and has raised walks leading to a platform for a central pavilion. The plan of Arga was typical of Islamic cities: a citadel on the edge of a fortified enclosure (which could be used to grow food in times of siege) adjoining a walled town. At Agra the fortified enclosure is now used by the army and is not accessible to the public.
