  Yazd, a historical City"
A historical city which regrets never having been a capital while so many now forgotten ones were, Yazd commemorates by unusual monuments the importance given it by scores of scientists and thinkers in past centuries.
 
  Jami's Mosque
The Friday Mosque crowned by a pier of minarets, the highest in Persia, the portal's facade is decorated from top to bottom in dazzling tilework, predominantly blue in color. Within there is a long arcades court where, behind a deep-set south-east Ivan, is a sanctuary chamber. This chamber, under a squat tiled dome, is exquisite decorated with faience mosaic: its tall faience Mihrab, dated 1365, is one of the finest of its kind in existence. The Mosque was largely rebuilt between 1324 and 1365, and is one of the outstanding 14th century buildings in Persia. The tilework has recently been skillfully restored and a modern library built to house the mosque's valuable collection of books and manuscripts.
 
  Yazd, Bazaar
Bazaar Entrance, 19th century. This incredibly imposing bazaar entrance was an excuse for a magnificent display of ostentation. The bazaar itself is comparatively small, but the entrance is undoubtedly the grandest in Iran. The twin minarets rival those of the Jami' Mosque, while the entire facade is decorated with glazed titles and plaster stalactite vaulting. The wooden framework is decorated and carried during the procession for the mourning for Imam Husayn.
 
  Zoroastrian Fire Temple
This is Yazd's "Fire Temple". The institutes meet there, but nobody apart form the Grand Priest, a descendant of the Magi, reciting the Avesta, has access to the Saint of Saints where for the past 3000 years a fire burns in a brazen vessel. The fire itself is a representation of what is good.
 
  Water House
Enormous domes starting at ground level and also surmounted by arivents act as protective roofs for deep water-tanks six, eight or ten meters below the street level, which are reached by staircases. These buildings are so clean and well cared for that they look as if they were build yesterday.
 
  Vagt u Sa'at Square
This building is in fact the tomb of Sayyid Rukn ad-Din, and is all that remains of a complex erected to his orders known as the Institute of Time and the Hour whose mechanical devices made it one of the wonders of the age.
