On what is now a windblown patch of grassland enclosed in colossal walls and dotted with ancient cathedrals, there was once a great city—the ancient Armenian capital of Ani. You can still see the lines of its streets outlined in the turf, and inside the granite churches you can make out the fading faces of saints and kings painted on the ceilings more than a millennium ago. On one side of the city, a dramatic single - span bridge, now ruined, brought the Silk Road across the gorge of the Akhurian River. On the other, the road wound on across the Anatolian plains to Constantinople and the great trading cities of the Mediterranean. Once, Ani was close to the center of the world. Being at the crossroads of empires made Ani as large and as wealthy as Venice. Today, only a few determined tourists make it to this remote patch of borderland on Turkey’s frontier with Armenia ( it’s just four years since it became possible to visit the site without special permission from the military). It feels like the end of the earth.
The Seljuk Turks took Ani from the Armenians in the middle of the 11th century. Today, in Ani and all over ancient Armenia—now eastern Turkey, there’s a feeling that the place has been ahandoned by history, and by the people who made the place’s history. Lately, though, the governments of both Turkey and Armenia have been feeling their way toward reconciliation. The locals care much more about cross - border trade, cheaper electricity supplies and tourism. And the elements of diplomacy have been falling into place: a friendly soccer match, an equally friendly return match, and presidential visits.
Perhaps Ani supplies a clue as to how the future world might look. Ani’s two greatest cathedrals served Christianity for less than 70 years before being converted to mosques by the Seljuks. But the Turkish conquerors left most churches as they were, side by side with new mosques. Like all the great trading cities of the medieval world, Ani was a promiscuous mix of faiths and peoples—a crossroads, a meeting point, a place of equal footing. Perhaps with the opening of the border, this comer of the world could start to become a crossroads again, instead of a lonely dead end.

A:Now, Ani is a city in Armenia. B:Now, Ani is a city in Turkey. C:The Seljuk Turks invaded Ani in the late 11 th century. D:The Seljuk Turks invaded Ani in the beginning of 11 th century.
