Mosul, Iraq
The tomb, the final resting place of biblical prophet Jonah, was revered by Muslims, Jews, and Christians alike, and a popular destination for religious pilgrimages. During its history, it has been the site of an ancient Assyrian palace and temple, a Christian church, and a 21st-century mosque. In July 2014, terrorist group ISIS blew up the mosque, destroying the tomb, plundering the site, and looting hundreds of items. While much of the site is still damaged, Iraqi archaeologists have found a previously undiscovered palace built in the seventh century B.C. for an Assyrian king, and a planned reconstruction is underway and expected to be completed in 2023.
