The Baha ad-Din complex is a cult ensemble located in the suburban area of Bukhara. The complex served as the center of the Nakshbandi dervish order. Its head, Sheikh Bahauddin Nakshband, died in 1389 and was buried near the village of Kasri Arifon (now in the Kagan region) near Bukhara.
It consists of a madrasah, two mosques and a minaret.
The ensemble of Baha ad-Din adopted the characteristic of the 16th century. forms of combination of the necropolis with the ceremonial building; in 1544, Abd al-Aziz-khan I decorated the sheikh's burial place in the form of a ground crypt - a dakhma with a marble carved fence on top, and at a distance - the largest known khanaka building.
The mother of the ruler Abulfeyz Khan (1711-1747) ordered the construction of a mosque with two aivans (terraces) at her own expense, and in the 19th century Nasrullah Khan's vizier Hakim Kushbegi built another mosque. The minaret (tower) was built in 1720.
