Agra, once the capital of the Mughal Empire during the 16th and early 18th centuries, is one and a half hours by express train from New Delhi. Tourists from all over the world visit Agra to make a pilgrimage to Taj Mahal, India’s most famous architectural wonder, in a land where magnificent temples and edificies abound to remind visitors about the rich civilization of a country.

The postcard picture of Taj Mahal does not adequately convey the legend, the poetry and the romance that shroud what Rabindranath Tagore calls "a teardrop on the cheek of time". Taj Mahal means "Crown Palace" and is in fact the most well preserved and architecturally beautiful tomb in the world. It is best described by the English poet, Sir Edwin Arnold, as "Not a piece of architecture, as other buildings are, but the proud passions of an emperor’s love wrought in living stones." It is a celebration of woman built in marble and that’s the way to appreciate it.

Taj Mahal stands on the bank of River Yamuna, which otherwise serves as a wide moat defending the Great Red Fort of Agra, the center of the Mughal emperors until they moved their capital to Delhi in 1637. It was built by the fifth Mughal emperor, Shah Jahan in 1631 in memory of his second wife, Mumtaz Mahal, a Muslim Persian princess. She died while accompanying her husband in Burhanpur in a campaign to crush a rebellion after giving birth to their 14th child.

When Mumtaz Mahal was still alive, she extracted a promise from the emperor that he build the Taj after her death. He kept the promise. Construction began in 1631 and was completed in 22 years. Twenty thousand people were deployed to work on it. The material was brought in from all over India and central Asia and it took a fleet of 1000 elephants to transport it to the site. It was designed by the Iranian architect Ustad Isa and it is best appreciated when the architecture and its adornments are linked to the passion that inspired it. It is a "symbol of eternal love".

The Taj rises on a high red sandstone base topped by a huge white marble terrace on which rests the famous dome flanked by four tapering minarets. Within the dome lies the jewel-inlaid cenotaph of the queen. So exquisite is the workmanship that the Taj has been described as "having been designed by giants and finished by jewellers". The emperor was deposed by his son and imprisoned in the Great Red Fort for eight years but was buried in the Taj. During his imprisonment, he had a view of the Taj.

As a tribute to a beautiful woman and as a monument for enduring love, the Taj reveals its subtleties when one visits it without being in a hurry. The rectangular base of Taj is in itself symbolic of the different sides from which to view a beautiful woman. The main gate is like a veil to a woman’s face which should be lifted delicately, gently and without haste on the wedding night. As one stands inside the main gate of Taj, his eyes are directed to an arch which frames the Taj.

The dome is made of white marble, but the tomb is set against the plain across the river and it is this background that works its magic of colours that, through their reflection, change the view of the Taj. The colours change at different hours of the day and during different seasons. Like a jewel, the Taj sparkles in moonlight when the semi-precious stones inlaid into the white marble on the main mausoleum catch the glow of the moon. The Taj is pinkish in the morning, milky white in the evening and golden when the moon shines. These changes, they say, depict the different moods of woman.

The Taj has a life of its own that leaps out of marble, provided you understand that it is a monument of love. As an architectural masterpiece, nothing could be added or substracted from it.
