    Taj Mahal has become one of the most famous tourist sites in India. It is called the Taj Mahal, meaning "Crown of the Palace". It is located in Agra. Agra is a city in north central India.

    Work on the tomb began in 1632. It took more than twenty years to build. Shah Jahan hired 20,000 men to construct the palace-like tomb. The building is made of white marble and sits on a base of red sandstone. There are tall towers, called minarets, standing 133 feet tall at each corner of the building. The minarets tilt slightly away from the building. This is so they will not fall on the tomb in the event of an earthquake. A huge dome was constructed over the center of the building. Precious stones were placed into the walls. They make the tomb sparkle at different times of the day. A special style of writing called calligraphy decorates the walls of the tomb. A long water pool was built outside the building and lined with trees and flowers. At certain times of the day, the beautiful Taj Mahal is reflected in the pool. The colors of the tomb change. They are pinkish in the morning, white in the evening, and golden colors when the moon shines.

    Today, the bodies of Shah Jahan and his wife lie beside one another in this monument to love. Some call the Taj Mahal the eighth wonder of the world.
