Agra is a city in northern India’s Uttar Pradesh state. It’s home to the iconic Taj Mahal, a mausoleum built for the Mughal ruler Shah Jahan’s wife, Mumtaz Mahal (who died in childbirth in 1631). The imposing main building features a massive dome and intricately carved white marble inlaid with precious stones. This is set behind a reflecting pool inside a courtyard defined by 4 minarets.
