Tepe Sialk in Kashan, Iran, is a mud-brick platform dating to the early third millennium BCE.
It is possibly a support for some kind of building standing atop the platform but not necessarily a temple.
Some have speculated it is a ziggurat, but the evidence does not point to that kind of structure.
At the site, there are actually two structures (necropolises) at Sialk situated several hundred feet from each other.
