Remains of the tomb of the Ottoman sultan Suleiman the Magnificent, who died in 1566 while his troops were besieging the fortress of Szigetvar in southern Hungary, are believed to have been found, a Hungarian historian has said.

Norbert Pap, of the University of Pecs, said the tomb is understood to have been built over the spot where Suleiman’s tent stood and where he died. Pap said objects suggesting it was Suleiman’s tomb were found during the dig, as well as other historical evidence, although more excavations were needed to confirm the find.

“We have data which all points in the same direction,” Pap said at a presentation of the latest findings on Wednesday. “That is why we say ‘in all certainty’, because there is no sign pointing in another direction. But more confirmation is needed, as this is a very delicate topic.”
