The Taj Mahal, described as the most extravagant monument ever built for love, has become the de facto tourist emblem of India. This poignant Moghul mausoleum was constructed by Emperor Shah Jahan in memory of his second wife Mumtaz Mahal, whose death in childbirth in 1631 left the emperor so heartbroken that his hair is said to have turned gray overnight. Construction of the Taj began in the same year and was not completed until 1653.

Although the Taj is amazingly graceful from almost any angle, it's the close-up detail which is really astounding. Semiprecious stones are inlaid into the marble in beautiful patterns using a process known as Pietra Dura. The precision and care which went into the Taj Mahal's design and construction is just as impressive whether you view it from across the river or from arm's length.

The city's other major attraction is the massive red sandstone Agra Fort, also on the bank of the Yamuna River. The auricular fort's colossal double walls rise over 20m (65ft) in height and measure 2.5km (1.55mi) in circumference. They are encircled by a fetid moat and contain a maze of superb halls, mosques, chambers and gardens which form a small city within a city. Unfortunately not all buildings are open to visitors, including the white marble Pearl Mosque, regarded by some as the most beautiful mosque in India.

Other worthwhile Moghul gems include the Itimad-ud-daulah, many of whose design elements were used in the construction of the Taj, and Akbar's Mausoleum at Sikandra which blends Islamic, Hindu, Buddhist, Jain and Christian motifs, much like the syncretic religious philosophy Akbar developed attempted to do.
