Set against a backdrop of snow-capped Caucasus peaks, Sheki developed as a trading centre with many caravanserais located within the city. Two still remain: the Upper and the Lower Caravanserais, built in the eighteenth century. A city with a long history, Sheki is a must for architecture buffs. The Palace of the Sheki Khans is a fascinating building featuring intricate mosaics made from glass imported from Venice; not a single nail was used in its construction. To the north of the city you’ll find the ruins of what was once considered an impregnable fortress. Its name, “Gelersan - Gerarsan” translates as “you will come and see”.
