The Mausoleum of Khoja Ahmed Yasawi, a UNESCO World Heritage Site in Kazakhstan, is a 14th-century architectural masterpiece built under Timur’s patronage to honor the revered Sufi poet and mystic. Constructed between 1389 and 1405, the unfinished structure showcases innovative Timurid design with its massive brick dome, intricate tilework, and experimental vaults, influencing later Islamic architecture. It remains a significant pilgrimage site, housing 35 rooms, including a library and underground mosque, and stands as a cultural and spiritual landmark.
