UZBEKISTAN

A very nice cover from Uzbekistan (my 2nd one from this country), depicting a complete set of 2 stamps + a miniature sheet issued in 2013 on topic "Silk Road".
One stamp illustrates the historic centre of Bukhara, situated on the Silk Route, a city with more than 2.000 years old, the most complete exemple of a medieval city in Central Asia. The other stamp shows the "Itchan Kala", the inner town of the old Khiva oásis, which was the last resting-place of caravans before crossing the desert of Iran. Although few very old monuments still remain, it is a coherent and well-preserved example of the Muslim architecture of Central Asia. Finally, the miniature sheet displays a general view of the Old city of Khiva.
All this places are inscribed at Unesco as World Heritage sites.
