Agra Fort

Near the gardens of Taj Mahal stands the important 16th-century Mughal monument known as the Red Fort of Agra. This powerful fortress of red sandstone encompasses within its 2.5-km-long enclosure walls, the imperial city of the Mughal rulers. The forbidding exteriors of this fort hide an inner paradise. There are a number of exquisite buildings like Moti Masjid - a white marble mosque akin to a perfect pearl; Diwan-E-Am, Diwan-E-Khaas, Musamman Burj - where Mughal Emperor Shah Jahan died in 1666 A.D., Jahangir's Palace, Khaas Mahal and Sheesh Mahal. Agra Fort, an excellent example of Mughal architecture, is one of the few UNESCO World Heritage Sites in India.
The construction of the Agra fort was started around 1565, when the initial structures were built by the Mughal Emperor Akbar, and subsequently taken over by his grandson Shah Jahan, who added most of the marble creations to the fort. The fort is crescent shaped, flattened on the east with a long, nearly straight wall facing the river. It is ringed by double castellated ramparts of red sandstone, punctuated at regular intervals by bastions. A 9m wide and 10m deep moat surrounds the outer wall. An imposing 22m high inner wall imparts a feeling of invincible defensive construction. 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.
The fort had originally four gates, two of which were later walled up. Today, visitors are allowed entry only through the Amar Singh gate. Jehangir Mahal is the first notable building that the visitor sees as he enters through Amar Singh gate. Jehangir was Akbar's son and the heir to the Mughal throne. Jehangir Mahal was built by Akbar as the women's quarters. It is built of stone and is simply decorated on the exterior. Ornamental Persian verses have been carved on a large stone bowl, which were probably used to contain fragrant rose water. Akbar built a palace, adjacent to Jehangir Mahal, for her favourite queen Jodha Bai.
Built by Shah Jahan, entirely of marble, the Khaas Mahal demonstrates distinctive Islamic-Persian features. These are well blended with a striking range of Hindu features such as chhatris. It is considered to be emperor's sleeping room or 'Aramgah'. 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 pavillion. It boasts of its openness, elevation and cool evening breezes. This is where Shah Jahan lay on his deathbed, gazing at the Taj.
Sheesh Mahal or the Glass Palace is the finest example of decorative water engineering in the hammams. It is believed to have been the harem or the dressing room, and its walls are inlaid with tiny mirrors which are the best specimens of the glass-mosaic decoration in India. To the right of Sheesh Mahal is Diwan-I-Khaas, the hall of Private Audience. The marble pillars are inlaid with semi-precious stones in delightful floral patterns. Adjacent to this, is the Mammam-E-Shahi or the Shah Burj, used as the summer retreat.
The Diwan-E-Am used to house the famous Peacock Throne, which was taken to the Red Fort when Shah Jahan moved his capital to Delhi. The throne alcove is of richly decorated white marble. Nagina Masjid, built by Shah Jahan, was the private mosque of the ladies of the court. Moti Masjid or the Pearl Mosque is the prettiest structure at Agra Fort. The building is presently closed for visitors. Near Moti Masjid is Mina Masjid, which seems to have been constructed by Shah Jahan strictly for his private use.
