Soltaniyeh is a city in Zanjan province that is dotted with ancient ruins. The most significant and impressive of these ruins, however, is the Dome of Soltaniyeh. The Dome, which is also sometimes referred to as the Mausoleum of Il-khan Öljeitü or Muhammad Khodabandeh, was even more impressive when it was first completed all the way back in 1312 AD. This UNESCO World Heritage Site is considered a key monument in the history of Islamic architecture since it is the oldest double-shell dome in the world.
