The Dor-ut Tilovat memorial complex came into existence following the death of Shamsiddin Kulal in 1370-1371. Kulal was a revered religious leader, the founder of Sufism, and the spiritual guide to Emir Taragay, Timur, and Bahauddin Naqshbandi. His burial site quickly became a pilgrimage destination for his many followers.
Adjacent to Sheikh Kulal’s tomb was the Dor-ut Tilovat madrasa. Emir Taragay’s remains were later relocated to one of its chambers. Under Timur’s rule, Kulal’s tomb was adorned with onyx marble slabs. Later, during Ulughbek’s reign, a domed mausoleum was constructed over Shamsiddin Kulal’s resting place, replacing an earlier, simpler structure. In 1435, the Ko’k-Gumbaz (Blue Dome) mosque was built directly opposite the mausoleum, aligned on the same axis. An inscription on the mosque’s portal reveals that Ulughbek commissioned its construction in honor of his father, Shakhrukh. This mosque also served as Shahrisabz’s Friday Mosque.
