An inscription with fourteen Edicts of Ashoka is found on a large boulder within 2 km of Uperkot Fort[2]. The inscriptions carry Brahmi script in Pali language and date back to 250 BCE On the same rock are inscriptions in Sanskrit added around 150 CE by Mahakshatrap Rudradaman I, the Saka (Scythian) ruler of Malwa, a member of the Western Kshatrapas dynasty[3]. Another inscription dates from about 450 CE and refers to Skandagupta, the last Gupta emperor. Old rock-cut Buddhist "caves" in this area, dating from well before 500 CE, have stone carvings and floral work. There are also the Khapra Kodia Caves north of the fort, and the Babupyana Caves south of the fort.
