Institute for Science and International Security (ISIS) has obtained satellite imagery from DigitalGlobe of two possible locations of the gas centrifuge uranium enrichment facility under construction near Qom, Iran. Both are tunnel facilities located within military compounds approximately 30-40 kilometers away from Qom.
This is one of the two possible locations. The other one is also
mapped on this site.
The link (scroll down on screen) mentions Fordo; and has a picture of this site.
