The Taj Mahal is the most extravagant monument built for eternal enduring love. It is India's most famous tourist attraction. Taj Mahal is a mausoleum known for its reflective pond leading to the fabulous monument. Completed in 1653, it was built by the Emperor Shah Jahan in memory of his second wife, Mumtaz Mahal, who died in childbirth. It was completed in 22 years, employed twenty thousand workers and was designed by the Iranian architect Istad Usa. Revered for its grace and detailed beauty, the Taj Mahal is considered to be the zenith of Indo-Persian architecture and the elaborate marble designs are inlaid with semi-precious stones such as jade, crystal, Turquoise and coral. The changing light and shadows affect the colour and patterns of the Taj Mahal. The Taj is pinkish in the morning, milky white in the evening and golden when the moon shines.
