Taj Mahal- mausoleum-mosque, located in Agra, India, on the bank of the river. Yamuna Inside the mausoleum are two tombs - the Shah and his wife. In fact, the place of burial is in the same place and the tomb, but under the ground. Construction time is about to 1630-1652 years. The Taj Mahal is a five-domed building height of 74 m. On a platform with four minarets at the corners (they are slightly tilted to the side of the tomb so that in case of failure as not to damage it), which adjoins the garden with fountains and a swimming pool. The walls are lined with polished marble, translucent (brought for the construction of 300 km) inlaid with semi-precious stones. We used turquoise, agate, malachite, carnelian and others. Marble has the peculiarity that in bright daylight it looks white, it looks at the dawn rose, and in the moonlight silver. On the left side of the tomb is a mosque of red sandstone. On the right a replica of the mosque. The whole complex has an axial symmetry. The tomb has a central symmetry with respect to the tomb of Mumtaz Mahal. The only violation of this symmetry is the tomb of Shah Jahan, that built there after his death.
