I think the world looked on in horror when ISIS set about destroying Palmyra, which I think is in Syria? Also remember reading about the Taliban blowing up a very ancient Buddhist structure in Afghanistan.
I certainly hope that Trump doesn't destroy any of the amazing historical sites in Iran, a country full of antiquities and a very rich culture. My neighbour, who returned to Iran a couple years ago, although her daughter born and bred in England still lives next door, however not being imbued in the culture as her mother and father were, both Zoroastrian an incredibly ancient monotheistic religion that pre dates Christianity, isn't that interested in the country of her heritage. When her mother was next door we did talk about Iran quite a lot, she cooked a Persian meal for us which was pretty amazing. It's a country that has so much potential if the world were a different place. Before the Ayatollahs took over it offered a diverse range of activities from skiing to sea side holidays on the Caspain along with all those wonderful historical sites.
I don't agreee that only Western sites matter, Persia in ancient times were often at war with Greece and like Turkey they were a link between Western Europe and Asia. I think it's a tragedy for mankind to lose any ancient site or monument.
As for the Moorish sites in southern Spain we went to Seville and Cordoba last year, amazing! having already seen the Alhambra a few years ago, those for me are what makes Spain special, certainly not the Costas, parts of which can be pretty dire.
