I had an amazing journey to Turkestan last summer. Turkestan, the ‘land of the Turks’ is located in Syr-Darya Valley. I highly recommend this sightseeing to everyone traveling in Kazakhstan. Turkestan is a number one destination with its real gem of Turkic architecture. Kozha Akhmed Yasaui Mausoleum. It is an unfinished mausoleum in the city of Turkestan, in southern Kazakhstan. Khoja Ahmed Yasawi was the 12th-century head of a regional school of Sufism, a mystic movement in Islam which began in the 9th century. He was died in 1166. The Mausoleum of Khoja Ahmed Yasawi was later built on the site of his grave by Timur in Turkistan City.
