Soltaniyeh Dome: The World’s Largest Brick Dome

A UNESCO World Heritage site, the 14th-century Soltaniyeh Dome, also known as Mausoleum of Oljaytu is highly recognized as an architectural masterpiece particularly due to its innovative double-shelled dome and elaborate interior decoration.

The very imposing dome stands about 50 meters tall from its base. Covered with turquoise-blue faience tiles, the stunning structure dominates the skyline of Soltaniyeh, an ancient city in Zanjan province, north-western Iran.
