The Tomb of Cyrus at Pasragardae has been the subject of a number of controversies to date. The most recent one pertians to questionable “restoration” methods used by a local Iranian team led by Hassan Rahsaz. The latter was interviewed live along with Kaveh Farrokh in a televised debate in the Voice of America program “Meezgerd ba Shoma” (Roundtable with You) on December 29, 2008:

Farrokh noted in the interview that the only way to resolve the debates, questions and doubts is to allow neutral 3rd party non-governmental archaeologists and Iranologists from inside of Iran and abroad to visit the site and examine it up close (i.e. Professor David Stronach, Professor Richard Nelson Frye, etc.).
