Qutub minar

Qutbuddin Aibak, the first Muslim ruler of Delhi, inspired by Jam's tower located in Afghanistan and desirous of going beyond it, started the reconstruction of Qutub Minar in 1193 by breaking the observatory due to the craze of spreading Islam, but only its base.  Got it made.  His successor Iltutmish extended three storeys in it. In 1351 Firoz Shah Tughlaq built the fifth and final floor.  The tower is made of red sandstone, on which fine engravings of the verses of the Quran and flower vines have been made, which break the flower vines and make Arabic words, there are no verses of the Quran. 
 Qutub Minar is built on the remains of the ancient fortress Lalkot in the ancient city of Delhi, Dhillika.  Dhillika was the capital of the last Hindu kings Tomar and Chauhan.  The original name of Qutub Minar is Vishnu Pillar which was built not by Qutubdin but by one of the Navratnas of Emperor Chandragupta Vikramaditya and astronomer Varahamihira.  The settlement near Qutub Minar is called Mehrauli.  It is a Sanskrit word called Mihir-Aveli.  
It can be said about this town that the famous astronomer Mihir (who was in Vikramaditya's court) lived here.  He was accompanied by his assistants,

mathematicians and technologists.  They used this so-called Qutub Minar for astronomical calculations, studies.  When viewed from a two-seater airplane, the tower shows a 24 petal lotus flower.  Each of its petals looks like a hora or a 24-hour dial.  The building of a lotus flower with twenty-four petals is completely a Hindu idea.  It cannot be associated with any dry part of West Asia which does not originate there.  

Around this tower were mandapas or domed buildings for 27 constellations or constellations dedicated to the Hindu zodiac.  Qutbuddin left an account in which he wrote that he had destroyed all these pavilions or vaulted buildings, but he did not write that he built a tower.  Muslim raiders used to take out the stone-dressing or stone cover of Hindu buildings and change the face or front part of the idol to make it the front part written in Arabic.  Sanskrit details on the pillars and walls of many complexes can still be read. The entrance to this tower is in the north direction, not in the west, while the west is of importance in Islamic theology and tradition. 
It was an astronomical observation tower.  .  It is written in Sanskrit in Brahmi script on iron pillars rusted nearby that this pillar of Vishnu was built on a hill called Vishnupada Giri.  It is clear from this description that the statue of Vishnu lying in the temple situated in the center of the tower was destroyed by Mohammad Ghori and his slave Qutubuddin.  The pillars were built to honor a Hindu king's victories in the east and west.  The pillar had seven floors which indicated a week, but now the pillar has only five floors.  The sixth was dropped and re-erected on the adjacent ground.  On the seventh floor is actually a four-faced statue of Brahma holding the Vedas in his hands before he created the world. Above the statue of Brahma was a white marble umbrella or parasol carved with the gold hour figure.  .  The top three floors of this tower were ruined by the idolized Muslims who hated the statue of Brahma. 
 
Muslim attackers also destroyed the idol of Vishnu resting on the bed on the ground floor.  The iron pillar was called the Garuda flag or Garuda pillar.  It was considered to be the sentinel of Vishnu's temple.  The temples of 27 nakshatras in one direction had an oval enclosed part. The circle of the tower is made up of precisely 24 turns, and it consists of alternating turns, circle shapes and triangle shapes, respectively.  This shows that the number 24 had social significance and gave prominence to the campus.  It has 27 jhiris or holes for light to come.  If this thing is considered with the 27 constellation pavilions, then there is no doubt that the tower was an astronomical observation column.
