The principal monument is Stupa 1 dated to the 2nd century and 1st century BC. These Buddhist sanctuaries were active Buddhist religious monuments, which flourished until the 12th century. The sanctuary has a plethora of monolithic pillars, palaces, temples and monasteries in different status of preservation. It was inscribed as a World Heritage Site by UNESCO on January 24, 1989, for its unique cultural importance. It was discovered only in 1818 in a deserted state of preservation.
