Masjid (Xoja Zayniddin majmuasi)

This mid-16th-century mosque stands at a street junction about 300 meters southwest of Bukhara's Poi-Kalyan square, within the old walled inner city. It belongs to a building type known as mosque-khanaka, combining a place of congregational prayer with a Sufi hospice used for ceremonies involving choral chanting and music. Despite housing one of the largest domed interiors in Bukhara, neither the mosque's original patron nor its architect is recorded in surviving sources. The building connects on one side to the surrounding residential quarter through a shaded aiwan and a large stone-paved water basin that supplied drinking water to the neighborhood, linking the sacred structure directly to the daily life of the mahalla around it. The mosque is usually referred to by the name of the Sufi sheikh Khoja Zayniddin and remains one of the lesser-publicized but architecturally significant monuments of Bukhara's historic core.
