Located in Agra, Uttar Pradesh in India, the Taj Mahal is widely recognized as "one of the universally admired masterpieces of the world's heritage." It became a UNESCO World Heritage Site in 1983. It is a great example of Mughal architecture. The white domed marble mausoleum offers a different (always amazing) view from dawn to night. The building looks silver under the moonlight, turning it into a fairyland. As one of the most popular attractions in India, it attracts 2 to 4 million visitors every year.
