The mausoleum of Oljaytu was constructed in 1302–12 AD in the city of
Soltaniyeh, the capital of the Ilkhanid dynasty. The Dome of
Soltaniyeh is the biggest brick dome in the world and the Mausoleum of Ilkhan Oljaytu.
The structure is a very exquisite mosque which is well-known in the world from the viewpoint of architecture, interior design and space.
Situated in the province of
Zanjan,
Soltaniyeh is one of the outstanding examples of the achievements of Persian architecture and a key monument in the development of its Islamic architecture.
The octagonal building is crowned with a 50 m tall dome covered in turquoise-blue faience and surrounded by eight slender minarets. It is the earliest existing example of the double-shelled dome in
Iran.
The mausoleum’s interior decoration is also outstanding and scholars such as A.U. Pope have described the building as ‘anticipating the
Taj Mahal’.
The dome is located 30 km east of
Zanjan ...see more inside the rampart of the old city of Soltaniyeh.
It is an octagonal building, each side of which is almost 80 meters. The Soltaniyeh Dome is built in the Arg city or old fortification of Sultaniyeh, the capital of Oljaytu, an Ilkhan ruler.
