GATEWAYS: 
  The fort had originally four gates, two of which were later walled up. Delhi 
  Gate in the west is fortified by massive octagonal towers and faces the bazar 
  and leads to the Lama Masjid in the city. Its architectural plan was imperviously 
  devised to put the defenders in an advantageous position. 
  
  Delhi gate is now closed for visitors. The Amar Singh Gate lies to the South 
  and is defended by a square bastion flanked by round towers. It had a crooked 
  entrance with dangerous trap points and a steep rise. Its Naubat Khana Court 
  with pillared pavilions is an impressive structure. Visitors are allowed entry 
  through this gate only. 
The construction of the Agra fort was started around 1565 when the initial structures 
  were built by Akbar. Shah Jahan replaced most of these with his marble creations. 
  Some however survived, among them are- Delhi Gate, Amar Singh Gate, Akbari Mahal 
  and the Jahangiri Mahal. 
The fort is crescent-shaped, flattened on the east with a long, nearly straight 
  wall facing the river. It has a total perimeter of 2.4 km, and is ringed by 
  double castellated ramparts of red sandstone punctuated at regular intervals 
  by bastions. A 9mt. wide and 10mt.deep moat surrounds the outer wall. An imposing 
  22mt. high inner wall imparts a feeling of invincible defensive construction. 
  The route through the Amar Singh gate is dog-legged. The layout of the fort 
  was determined by the course of the river, which in those days flowed alongside. 
  The main axis is parallel to the river and the walls bridge out towards the 
  city. 
  This is the first notable building that the visitor sees on his right hand side 
  at the end of a spacious lawn, as one enters through the Amar Singh Gate and 
  emerges out of the passage. It was built by Akbar as women's quarters and is 
  the only building that survives among his original palace buildings. It is built 
  of stone & is simply decorated on the exterior. 

The most important feature of the edifice are its ornamental stone brackets 
  which support the beams. In front is a large stone bowl which was probably used 
  to contain fragrant rose water. Ornamental Persian verses have been carved along 
  the outer rim, which record its construction by Jahangir in 1611 A.D. This elegant, 
  double storeyed palace reflects a strong Hindu influence with protruding balconies 
  and domed chhatries. 
  
  To the right of Jahangiri Mahal is Akbar's favourite queen Jodha Bai`s Palace. 
  In contrast to other palaces in the fort, it is rather simple. Through the slits 
  in the wall one can see the Taj. A better place to take photographs is further 
  on. 
  These formal, 85m square, geometric gardens lie to the left of the fort. During 
  Shah Jahan's time the beauty of the gardens was considerably enhanced by decorative 
  flower beds. 
  
  GOLDEN PAVILIONS: 
  The curved chala roofs of the small pavilions by the Khaas Mahal are based on 
  the roof shape of Bengali village huts constructed out of curved bamboo, designed 
  to keep off heavy rain. The shape was first expressed in stone by the Sultans 
  of Bengal. Originally gilded, these were probably ladies' bedrooms, with hiding 
  places for jewellery in the walls. These pavilions are traditionally associated 
  with Shah Jahan's daughters-Roshanara and Jahanara Begum. 
  
  Situated in between the golden pavilions is the Khaas Mahal. Built entirely 
  of marble by Shah Jahan, the palace demonstrates distinctive Islamic-Persian 
  features. These are well blended with a striking range of Hindu features such 
  as chhatries. It is considered to be emperor's sleeping room or' Aramgah', The 
  Khaas Mahal provides the most successful example of painting on a white marble 
  surface. 
  On the left of the Khaas Mahal is the Musamman Burj built by Shah Jahan. It 
  is a beautiful octagonal tower with an open pavilion. With its openness, elevation 
  and the benefit of cool evening breezes blowing in off the Yamuna river, this 
  could well have been used also as the emperor's bedroom. This is where Shah 
  Jahan lay on his death bed, gazing at the Taj. Access to this tower is through 
  a magnificently decorated and intimate appartment with a scalloped fountain 
  in the centre. The inlay work here is exquisite, especially above the pillars. 
  In front of the fountain is a sunken courtyard which could be flooded and in 
  the Sheesh Mahal opposite are further examples of decorative water engineering 
  in the hammams. 

 
  Opposite to the Mussaman Burj and just below the Diwan-e-Khaas hall is the Sheesh 
  Mahal or the Glass Palace. It is believed to have been the harem dressing room 
  and its walls are inlaid with tiny mirrors which are the best specimens of glass-mosaic 
  decoration in India. The Sheesh Mahal is composed of two large halls of equal 
  size, each measuring 11.15m x 6.40 m. Both are connected in the centre by a 
  broad arched opening and on the sides by two narrow passages. 
  
 
  To the right of Sheesh Mahal is Diwan-e-Khaas, the Hall of Private Audience. 
  Presently entry is not allowed inside Diwan-e-Khaas but the fine proportions 
  of the building can easily be appreciated. The marble pillars are inlaid with 
  semi-precious stones in delightful floral patterns. 
  
 To the right of Diwan-e-khaas is the Hammam-e-Shahi or the Shah Burj. Foreign 
  travellers who visited Agra during the reigns of Jahangir and Shah Jahan have 
  described these apartments as the Ghusal Khana (bathroom). It was not the Turkish 
  bathroom as is generally but erroneously supposed. It was really an "air-conditioned" 
  apartment, attached to the residential quarters and was used as a summer retreat. 
  Business of very confidential nature was conducted here. 
  
  Opposite to the Diwan-i-Khaas is the Macchhi Bhawan, the Fish Enclosure. The 
  emperor sat on the white marble platform facing this enclosure. It once contained 
  pools and marble fountains which were carried off by Jat Raja Surajmal to his 
  palace at Deeg. Around the Macchi Bhawan were the imperial offices.
