The desert city of Yazd is one of the oldest cities in Iran. It was founded in the 3rd millennium B.C. at an oasis between the deserts Dascht-e Kawir and Dascht-e Lut. Countless wind towers, which serve for cooling, characterize the townscape.

The Friday Mosque of Yazd was built in the 12th century AD and extended in the 14th century and is still in operation today.
It is an outstanding example of the Azari style in Persian architecture.
The blue tiled portal is crowned by a pair of minarets, the highest in Iran. Behind it there is a long arcaded courtyard, to the south-east of which an Ivan with an altar chamber is attached.

The Amir Chakmaq Mosque, built in the 13th century, no longer serves as a mosque today. With its three-storey façade, however, it provides an impressive setting for the square of the same name, which is inviting with numerous cafés and a large fountain.

In 2017 the old town of Yazd was declared a UNESCO World Heritage Site.
