10. The Great Mosque of al-Nuri, Mosul, Iraq
Famous for its leaning minaret, the 12th-century Great Mosque of al-Nuri was destroyed during the 2017 battle to retake Mosul from ISIS. Its loss signifies both spiritual and architectural devastation. Reconstruction efforts, led by UNESCO and funded by international partners, have been underway, with the mosque reopened in 2025.
