Yazd is one of the most ancient cities in the world, with a history spanning several millennia. The first mentions of a settlement at this location, known as Isatis, date back to the 3rd millennium BC, during the time of the Median Empire. According to one theory, the city received its current name in honour of the Sassanian ruler Yazdegerd I. Located in an oasis between the Dasht-e Kavir and Dasht-e Lut deserts, Yazd served as a vital stopover for caravans for centuries. The famous traveller Marco Polo, who visited the city in 1272, described it as a flourishing centre of trade and silk production.
The rise of Yazd is inextricably linked to its unique geographical position. Its distance from the main routes of conquerors allowed the city to avoid the large-scale destruction that befell many other Persian cities, for example, during the invasion of Genghis Khan. This contributed to Yazd becoming a sanctuary for scholars, architects, artists, and poets. Life in the harsh desert climate forced the local inhabitants to demonstrate remarkable ingenuity, creating unique architectural solutions: a system of underground water channels (qanats) to supply the city with water and the famous badgirs ("windcatchers") — towers for natural ventilation and cooling of buildings.
Since ancient times, Yazd has been and remains one of the key centres of Zoroastrianism — an ancient Iranian religion. Even after the spread of Islam, the city retained a large Zoroastrian community and its shrines, including the Fire Temple, where, according to tradition, the flame has been kept burning since 470 AD. The city's economy has historically relied on trade and crafts. Yazd was a crucial hub on the Great Silk Road, famous throughout the world for its exquisite fabrics, silk, and carpets, which were exported to India and Central Asia. This rich history and cultural heritage allowed the historic part of the city to be included in the UNESCO World Heritage List.
