Spread over an area of about 42 acres, the entire Taj Mahal complex is mainly divided into five parts - the main entrance, gardens, mosques, guest houses and the mausoleum of Empress Mumtaz with its four minarets.
The main square of the Taj Mahal is surrounded by walls on three sides like a fort. Outside the wall are the tombs of Shah Jahan's other wives and Mumtaz's favorite attendants. The walls are patterned within the walls. All the walls have been built into a dome-shaped structure, which is currently used as a museum. The main entrance of the Taj Mahal is made of marble stone with Mughal architecture and design. The main square houses the red mosque and the Mughal guest house in two separate structures.
There is a “charbagh” in the forecourt of the Taj Mahal. It is known as the Garden of Paradise. There are 16 separate flower gardens with high walls, tree-lined walkways and beautiful fountains. Between the Samadhi section and the main gate is a marble stone chowbachcha in which the entire Taj Mahal can be seen reflected in the water.
The interior of the mausoleum is decorated with octagonal carved semi-circular marble stones. Here is the tomb of Emperor Shah Jahan and his wife Mumtaz. Although these are only dummy tombs covered with a kind of screen of fine wire-worked Mandit marble. Dummy tombs 80 feet below the ground contain their actual tombs in sculpted ornate inscriptions. When the moonlight reflects on the tomb during the full moon, an otherworldly atmosphere is created around it.
Inside the Taj Mahal complex, verses of the Holy Quran are beautifully carved in geometric and floral designs on precious stones using the pitra dura technique.
It is said that during the last period Emperor Shah Jahan wanted to build another Taj Mahal on the bank of Yamuna River which is now known as “Kala Taj Mahal”. From here one can see various beautiful forms of Taj Mahal in the light of sun and moon. Built of black marble, this fort is connected to the Taj Mahal by a bridge.
And 1 mile away from the Taj Mahal, Agra Fort is located on the right side of the Yamuna River, which was a military fort during the Mughal period, but later became known as the residence of the royal family under the leadership of Shah Jahan, as well as a place for various royal activities.
