Third century BC Buddhist Stupa of Yamunanagar District, Haryana, a heritage monument

A stupa  is a mound-like or hemispherical structure containing relics (such as śarīra/mortal remains of Buddhist monks or nuns) that is used as a place of meditation.   A related architectural term is a chaitya, which is a prayer hall or temple containing a stupa. Such supas are common in places where Buddhism was in practice on a large scale. Stupas and ornamental Thoarnas are architectural features of  Buddhist places of worship. The stupa in the Ymunanagar district of Haryana state is an interesting one, simple in appearance,and not ornamental.  As in Hinduism in which prathakshana path (prakaram) is an important part of Hindu  temples, in  Buddhism,  Prakaram - circumambulatory or prathakshana is equally important. Going  clock-wise  around the sanctum on the prathakshana path has been an important  prayer ritual and devotional practice  in Buddhism as well since the earliest times. Hence, stupas always have a pradakhshina path around them.

Situated 3 km away from Jagadhri, in Yamunanagar  District the  old Buddhist Stupa (3rd century BC) is an important Buddhist site. The   8 meter tall  grand Tomb is  made of bricks, covering roughly an area of   100 sq meters near the village.  This mound  shaped  Buddhist stupa is a pretty old one built  by the great emperor Ashoka who converted to Buddhism after the tragic Kalinga war held in the present day Odisha state. The great Chinese traveler Hieun Tsang  and scholar confirms  the name of the builder.

When the Mauryan king Ashok was the ruler, during his heyday, the ancient city of Shrughna (modern sugh) became an important center of Buddhism.  The Chinese traveler in his travelogue mentioned about this city after his visit there, He said there was a big monastery and tens of stupas adorning the city.  The village Chaneti is close to Sugh, about 3 km and the  Stupa at Chaneti could be on of  those tens of topes referred to by the Chinese traveler.  In order to build mound -shaped stupa, the builders followed a simple method.    concentric layers were placed  one over the other,  leaving some space on the underlying layer, so that the whole structure should  assume  a hemispherical look. It is apparent this stpa is quite similar to  the Shahpur and Dharmarajika stupas at Taxila, yet another center for Buddhism, etc. On account of long passage of time, there is no trace of stone railings around the stupa here.  There is a likelihood the railings could have been made of wood  that wilted due to age and weather.  An interesting fact is atop the stupa the  square space  of about 1.5 mt. was found filled with earth. This was the place for harmika which bore the chhatravali (umbrella). The later additions perhaps during the Kushan period were the four shrines in four  cardinal  directions near the old  Prathakshna path. 
This stupa and the site are under the control of  the ASI (Archaeological Survey of India.
