Kankali Tila
An excavated mound that yielded a Jain stupa and hundreds of inscribed sculptures — the richest archaeological record of early Jainism.
Excavated in the 1880s and 1890s, Kankali Tila produced the remains of a stupa the inscriptions themselves describe as already ancient, together with sculpture spanning several centuries either side of the common era.
It matters because it is evidence rather than tradition: dated, inscribed, and independent of any later account. Most of what was found is now in the Mathura and Lucknow museums rather than on the site.
