An extension of Northern suite of Jodh Bai's Palace, Hawa Mahal is composed of beautiful jalied screens. Therefore, it is named as Hawa Mahal or Palace of Breeze. This kind of arrangement of screens keeps the interior cool and at the same time ensured purdah for ladies. This architectural feature is very common in these areas, which suffers extremely hot summers. This small but elegant building is double storeyed and entirely made up of red sand stone. The ground floor is composed of square columns in double rows and is open. The upper storey is covered with beautiful stone screens. Stairways have been provided on Eastern and Western side of Northern suite to approach this upper storey. The stone screens are 63.5 mm thick; the largest are 2.28m high and 1.74m broad.
Viaduct or Passage
The purpose of Viaduct passage was to allow the ladies of the imperial
Harem to go on outings in purdah. This has been provided from west of
the Hawa Mahal to the plain below. It was originally closed with
beautiful stone screens and extended upto Hathi pol and sangin Burj, but
now only a part of it is survived. The viaduct is 27' (8.23m) high
having arches of 11' (3.33m) in thickness, at regular intervals. These
arches are surmounted by beautiful kiosk, having usual dome and
octagonal drum on square base. The drum contains beautiful carved
Tulips. The viaduct is made up of rubble and plastered above. There are
evidences of a similar viaduct connecting Harem to Khwabgah of the
Emperor but it has now been destroyed. Some traces of these splendid
screens; with beautiful tracery work has been survived.
Hawa Mahal at Fatehpur Sikri is a part of the Imperial Harem.
