Let's explore the Taj Mahal, one of the Seven Wonders of the World. On the banks of the Yamuna River in Agra, Uttar Pradesh, India, this ivory-white marble mausoleum will certainly leave an impression. The Taj, seen in today's image, was commissioned in 1631 by Shah Jahan, the fifth Mughal emperor, to honour his beloved wife, Mumtaz Mahal. This tomb is the centrepiece of a huge complex, which also includes a mosque, a guest house and beautifully landscaped gardens surrounded by a grand wall. Laid out in a striking rectangular shape, the tomb is flanked by giant arches and alcoves that merge Indo-Islamic and Mughal architectural styles. This mausoleum draws inspiration from notable structures such as the Gur-e Amir in Samarkand, Uzbekistan, and Humayun's Tomb and Shah Jahan's Jama Masjid in Delhi.
