Sited south of Tehran, not far from the Khomeini International Airport, we'd caught a glimpse of the huge shrine the previous night as cameraman Pol Reygaerts and I were en route from the airport to downtown Tehran.
But it's only during daylight that the full scale of this enormous structure becomes apparent.
The shrine was built close to the graveyard which holds many of the 'martyrs' from the Iran-Iraq war of the 1980s, during which an estimated that half a million Iranians were killed.
The complex is still under construction and when finished will house a cultural and tourist centre, a university, a seminary, shopping malls, and gardens spread over 5,000 acres.

Small birds swooped overhead as we entered the inner chamber. Khomeini's remains lie in a sarcophagus under the main dome. On the back wall hangs a huge poster of the deceased leader, his eyes watching you watching him, framed by that recognisable black turban and white beard.
On either side, hang posters of Khomeini's two sons: Mustafa who died in Iraq in the 1970s, and Ahmed who died in the 1990s.
I stood and wondered: what relevance does Khomeini have in today's Iran? Will the new PresidentHassan Rouhani herald a new era for Iran? Are the calls for 'death to America going to fade? Will the nuclear talks in Geneva result in a new and more harmonious relationship with the West? Or will the current hopes simply fizzle out?
It was time to leave the Khomeini shrine and try to find out. ---None--- ...
