I love yazd....
I dont know why specially yazd.
Because Shiraz & Isfahan are meant to be the most Popular cities in Iran.
But for me Yazd is something else...Full of Art.
these two sketches are some of the Saabaats that you can find in many alleys in Yazd.(Sabaat=the shader which has several functions (structural function to carry the load of the two heavy opposite walls(as a bridge)).
& there is usually one or two small shop under it.)
The passenger who Might be very thirsty (hot temperature & no humid.)can rest & have a drink.(for free just you have to say Salavaat!) & enjoy Famous winds of the Yazd which blows into saabaat.
