Gonbad-e-Qabus is a monument, located in a city with the same name in north of Iran, Golestan province. Gonbad city is 93 Km north east from Gorgan, a sizeable town in northern Iran near the Caspian Sea.

The Gonbad-e-Qabus is actually a spectacular tomb tower, a stunning memorial to the remarkable Qabus, a prince, poet, scholar, general and the patron of the arts. He ruled the surrounding region at the turn of the 11th century and decided to build a monument to last forever.

The 55m (180ft) tower was completed on 1006, six years before Qabus was slain by an assassin.
