ناصر الدين القاجاري
The "Sardāb" of Caliph al-Mahdi ( 775–785) is preserved in Samarra, Iraq under a golden dome that was presented by Naser al-Din Shah Qajar and that was completed by Mozaffar ad-Din Shah Qajar in 1905. The tomb lies within the Al-Askari Mosque, one of the most important of Shia shrines. The mosque was badly damaged in a February 2006 bombing, presumably the work of Sunni militants.
