So many sights and sensation make up the country that is India. There are tiger parks and magnificent residences of Maharajahs, cool hills resorts with tea plantations with views of the distant Himalayas, there are the beaches of Goa and the pepper ports of the Malabar Coast to mention just a few. Here's a look at three of the marvels that define this vast and varied land - the Taj in Delhi, the Gateway of India in Mumbai, and the National Library in Kolkata.

Everyone visits the famous Taj Mahal in Agra, but in Dehli stands its precursor, Humayun's Tomb. Humayun was a Mughal Emperor during the 16th century. A native of Kabul, Humayun took the throne of Agra in 1530. He was a studious man and was fascinated by mathematics and astronomy. He also brought in Persian artists to add their stylistic influences to result in the classic Mughal form of architecture. He died in 1556 after falling down the steps of his library.

The garden tomb built by his widow Baga Begam in the years 1565 - 1569. It was India's first full-blown example of Mughal architecture in all its glory with the expansive gardens replete with water channels and fountains. 70 years later, this style of architecture was to reach its apex with the construction of the Taj Mahal.
