The aim of this paper is to examine the unclear connection between a well-known fortress (qal'a Istakhr), located in the Fars region on a mount not distant from the city of Istakhr, and the sa gunbadan (three domes), the name frequently given to the three mounts also standing on the plain of Marvdasht. The mix-up over the two subjects - fortress and mount(s) - may have arisen from the shape evoked by the term gunbad.
