The Taq-e Bostan complex in N.W. Iran is on UNESCO's Tentative List for World Heritage Status: Taq-e Bostan.

In 2007 I was invited to execute a conservation survey of the Sassanid Monuments of Taq-e Bostan, Kermanshah. The conservation works I proposed are to be commenced some time after the separately devised engineering works, which were completed in 2013.

A related series of discussion papers have been published 2013-2015 in both the Journal of Iranian Archaeology and Springer's Bulletin of Engineering Geology and the Environment.
