Deur Kothar's history dates back to the Mauryan and Sunga periods (3rd century BCE to 1st century BCE), as evidenced by the Brahmi inscriptions found within the caves. The site served as a Buddhist monastic complex, with monks residing and practicing their faith within the rock-cut shelters. The stupas discovered at the site indicate the presence of a thriving Buddhist community. Over time, the site was abandoned and gradually forgotten, succumbing to the elements. It was rediscovered in the late 20th century, and subsequent archaeological excavations have revealed its significance as an important center of early Buddhism in central India. The findings at Deur Kothar have contributed significantly to our understanding of the spread and influence of Buddhism in the region during ancient times.
