On Buddhist Stupa at Sanchi.

Sanchi stupa in Madhya Pradesh is one of the oldest standing structure in India (dated 2nd century B.C.E).  It was first built by king Ashoka of the Maurya Dynasty.  Later other dynasties such as the Sunga, Satwahana, and Malwa kings etc continued to protect and expand the Sanchi Stupa.  It is believed that Buddha relics are stored inside the stupa.  Hence, it is one of the most revered Buddhist monument in the world.  
Ashoka's wife was from Vidhesha- a town adjacent to Sanchi.  Ashoka himself is believed to have been a Governor of Vidhesha, before he became a great emperor.  Ashoka chose Sanchi to build the stupa as he found Sanchi to be a peaceful, quiet place, away from the hum drum of city life of Vidhesha.  These days, Sanchi is a bustling city with train whistles, temple and mosque announcements/songs on the loud speaker, people shouting while playing cricket in the near by parks, disturbing the peace and quiet of the stupa.  The location of the stupa is still very beautiful, with rolling hills and greenery around it as far as eye can see.  
The most beautiful part of the Sanchi Stupa are its torana (gateways).  These torana were made by the Sunga kings (1st century B.C.E) who are otherwise also known for giving India the most beautiful sculptures.  The women sculptures are damn beautiful and attractive!  I think, if it were not for the beautiful women sculptures, the beauty of the torana would not have been what it is with them.  The design of the gateway is very unique and beautiful i.e., parallel beams on top which extend artistically beyond the gateway.  The Sanchi Stupa is a must see for those who want to understand India and also for those who appreciate art.
