General Henry Taylor (1784–1876) who was a British officer in the Third Maratha War of 1817–1819, was the first known Western historian to document in 1818 (in English) the existence of Sanchi Stupa. The site was in a total state of abandon. The Great Stupa was clumsily breached by Sir Herbert Maddock in 1822, although he was not able to reach the center, and he then abandoned. Alexander Cunningham and Frederick Charles Maisey made the first formal survey and excavations at Sanchi and the surrounding stupas of the region in 1851. Amateur archaeologists and treasure hunters ravaged the site until 1881, when proper restoration work was initiated. Between 1912 and 1919 the structures were restored to their present condition under the supervision of Sir John Marshall.
