The Taj Mahal in Agra, India, which is taller than a 20-story building, is part of a complex of structures set within an elaborate garden, which measures 1,050 by 984 feet. The height of the main domed structure is 240 feet, and its interior walls are 82 feet high. Four minarets, about 130 feet in height, surround the main structure.
The base of the main structure is a cube measuring 180 feet on each side. The diameter of the dome is 60 feet. The dome itself is 115 feet high and rests on a cylindrical base which is about 23 feet in height. The entire complex is surrounded on three sides by red sandstone walls. The side of the complex facing the Yamuna River was left clear.
Construction on the Taj Mahal complex began in 1632, and was completed around 1653. It was built by Shah Jahan, the Mughal emperor, in memory of his wife Mumtaz Mahal. The Taj Mahal became a UNESCO World Heritage site in 1983.
