Architectural complexes[edit]

• 
  Po-i-Kalyan Complex. The title Po-i Kalan (also Poi Kalân, Persian: پای کلان meaning the "Grand Foundation") belongs to the architectural complex located at the base of the great minaret Kalân.
  
• 
  Kalyan minaret. More properly, Minâra-i Kalân, (Persian/Tajik for the "Grand Minaret"). Also known as the Tower of Death, as according to legend it is the site where criminals were executed by being thrown off the top for centuries. The minaret is the most famed part of the ensemble, and dominates over historical center of the city. The role of the minaret is largely for traditional and decorative purposes—its dimension exceeds the bounds of the main function of the minaret, which is to provide a vantage point from which the muezzin can call out people to prayer. For this purpose it was enough to ascend to a roof of mosque. This practice was common in initial years of Islam. The word "minaret" derives from the Arabic word "minara" ("lighthouse", or more literally "a place where something burn"). The minarets of the region were possible adaptations of "fire-towers" or lighthouses of previous Zoroastrian eras.^[27] The architect, whose name was simply Bako, designed the minaret in the form of a circular-pillar brick tower, narrowing upwards. The diameter of the base is 9 meters (30 feet), while at the top it is 6 m (20 ft). The tower is 45.6 m (150 ft) high, and can be seen from vast distances over the flat plains of Central Asia. There is a brick spiral staircase that twists up inside around the pillar, leading to the landing in sixteen-arched rotunda and skylight, upon which is based a magnificently designed stalactite cornice (or "sharif").^[28]

• 
  Kalân Mosque (Masjid-i Kalân), arguably completed in 1514, is equal to the Bibi-Khanym Mosque in Samarkand in size. The mosque is able to accommodate twelve thousand people. Although Kalyan Mosque and Bibi-Khanym Mosque of Samarkand are of the same type of building, they are different in terms of art of building. Two hundred and eighty-eight monumental pylons serve as a support for the multi-domed roofing of the galleries encircling the courtyard of Kalyan Mosque. The longitudinal axis of the courtyard ends up with a portal to the main chamber (maksura) with a cruciform hall, topped with a massive blue cupola on a mosaic drum. The edifice keeps many architectural curiosities, for example, a hole in one of domes. Through this hole one can see foundation of Kalyan Minaret. Then moving back step by step, one can count all belts of brickwork of the minaret to the rotunda.^[29]
