The Taj Mahal located in Agra, India, was built by Mughal emperor Shah Jahan in memory of his beloved wife, Mumtaz Mahal.

The Taj Mahal (also "the Taj") is considered the finest example of Mughal architecture, a style that combines elements from Persian, Indian, and Islamic architectural styles. In 1983, the Taj Mahal became a UNESCO World Heritage Site and was cited as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage."

While the white domed marble mausoleum is its most familiar component, the Taj Mahal is actually an integrated complex of structures. Building began around 1632 and was completed around 1653, and employed thousands of artisans and craftsmen. The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri. Lahauri is generally considered to be the principal designer.

The Taj Mahal attracts from 2 to 4 million visitors annually, with more than 200,000 from overseas. Most tourists visit in the cooler months of October, November and February. Polluting traffic is not allowed near the complex and tourists must either walk from parking lots or catch an electric bus. The small town to the south of the Taj, known as Taj Ganji or Mumtazabad, originally was constructed with caravanserais, bazaars and markets to serve the needs of visitors and workmen. Lists of recommended travel destinations often feature the Taj Mahal, which also appears in several listings of seven wonders of the modern world, including the recently announced New Seven Wonders of the World, a recent poll with 100 million votes.

The grounds are open from 6 am to 7 pm weekdays, except for Friday when the complex is open for prayers at the mosque between 12 pm and 2 pm. The complex is open for night viewing on the day of the full moon and two days before and after, excluding Fridays and the month of Ramzan. For security reasons only five items - water in transparent bottles, small video cameras, still cameras, mobile phones and small ladies' purses - are allowed inside the Taj Mahal.
