Taj Mahal, the most beautiful building in the world. In 1631 the emperor Shah Jahan built the Taj Mahal in memory of his wife Mumtaz, who died in childbirth. The white marble mausoleum at Agra has become the monument of a man's love for a woman.
Shah Jahan built the Taj Mahal as a monument to her memory and her fertility, but then relapsed into a life of scandalous behavior. This tomb was only one of hundreds of beautiful buildings that Shah Jahan erected, mostly at Agra and in the new Dehli that came into being under his planning.
Many architects have rated it as the most perfect of all buildings standing on earth. Three artists designed it: a Persian, an Italian, and a Frenchman. But the design is completely Mohammedan. Even the skilled artisans who built it were brought in from Baghdad, Constantinople, and other centers of the Muslim faith. For 22 years more than 20,000 workmen were forced to build the Taj. The Maharaja of Jaipur sent the marble as a gift to Shah Jahan. The building and its surroundings cost more than $200,000,000 in todays currency.

Agra Fort is a UNESCO World Heritage site located in Agra, India. The fort is also known as Lal Qila, Fort Rouge and Red Fort of Agra. It is about 2.5 km northwest of its much more famous sister monument, the Taj Mahal.Agra Fort is another dimension to the city that attracts tourists in hordes. Built by Akbar in Red Sandstone when he was through with the consolidation of his power after accession to power in 1654, Agra Fort worked both as a military strategic point as well as the royal residence. Many of the palaces inside the fort were later added by next generations of Mughal Emperors like Jahangir and Shahjahan.
The fort contains splendid palaces both in red sandstone and white marble built by two generations of prolific builders, Akbar and later on by Jahangir and Shahjahan. Of the nearly 500 Akbari buildings built in the Bengal and Gujarati traditions, only a few have survived, arrayed in a band on the riverfront.
