Sanchi, specially Stupa 1, has a large number of Brahmi inscriptions. Although most of them are small and mention donations, they are of great historical significance. James Prinsep in 1837, noted that most of them ended with the same two Brahmi characters. Princep took them as "danam" (donation), which permitted the decipherment of the Brahmi script,.[11][12]

An analysis of the donation records ^[13] shows that while a large fraction of the donors were local (with no town specified), a number of them were from Ujjain, Vidisha, Kurara, Nadinagar, Mahisati, Kurghara, Bhogavadhan and Kamdagigam.
The inscriptions include those from Maurya, Shunga/Satavahana (175 BC-15 AD), Kushana (100-150 AD), Gupta (600-800 AD, see Sanchi inscription of Candragupta II). The Ye Dharma Hetu inscription in Temple 45 may be dated to 9th century.
