Soltaniyeh situated in the Zanjan Province of Iran, some 240 km to the north-west from Tehran, used to be the capital of Ilkhanid rulers of Persia in the 14th century. Its name translates as "the Imperial". In 2005, UNESCO listed Soltaniyeh as one of the World Heritage Sites.
The central magnet of Soltaniyeh's several ruins is the Mausoleum of Il-khan Öljeitü, traditionally known as the Dome of Soltaniyeh. The structure, erected from 1302 until 1312, boasts the oldest double-shell dome in the world. Its importance in the Muslim world may be compared to that of Brunelleschi's cupola for the Christian architecture. The Dome of Soltaniyeh paved the way for more daring Iranian-style cupola constructions in muslim world, such as the Mausoleum of Khoja Ahmed Yasavi and Taj Mahal. Much of exterior decoration has been lost, but the interior retains superb mosaics, faience, and murals. Pope have described the building as “anticipating the Taj Mahal.”
The estimated 200 ton dome stands 49 meters (161 ft) tall from its base, and is currently undergoing extensive renovation.
