Date of issue 28 March 2008. The mausoleum of Khoja Ahmed Yasawi (Kazakh: Қожа Ахмет Яссауи кесенесі, Qoja Axmet Yassawï kesenesi) is an unfinished mausoleum in the city of Hazrat-e Turkestan, in southern Kazakhstan. In 2003, it became the first Kazakh patrimony to be recognized by UNESCO as a World Heritage Site. The present structure was commissioned in 1389 by Timur to replace a smaller 12th-century mausoleum of a famous Sufi master, Khoja Akhmet Yassawi (1103–1166). Master builders from Persia, led by Khwaja Hosein Shirazi[1], erected a 39-meter-high rectangular building in ganch, i.e., fired brick mixed with mortar and clay, and crowned it with the largest dome ever built in Central Asia — a double dome, decorated with green and golden tiles, which measures 18.2 metres in diameter and 28 metres in height. The building, one of the largest its time, was left unfinished upon the death of Tamerlane in 1405. The mausoleum has survived as one of the best-preserved of all Timurid constructions. It notably contains burials from the time of the Kazakh Khanate, including the tomb of Ablai Khan.
