Ildar Khanov in the context of "Temple of All Religions"

The Temple of All Religions (Russian: Храм всех религий, Tatar: Барлык диннәр гыйбәдәтханәсе, romanized: Barlıq dinnär ğibädätxanäse) or the Universal Temple (Russian: Вселенский храм) is an architectural complex in the Staroye Arakchino Microdistrict of Kazan, Russia. It consists of several types of religious architecture including an Orthodox church, a mosque, and a synagogue, among others. It is currently under construction since 1992, started by local artist and philanthropist Ildar Khanov (1940 - 2013). The structure now serves as a cultural center and a residence for Khanov's brother and sister, who both continue to serve as guides and supervisors of the complex.

Khanov was known for his efforts in the treatment of alcoholism, drug addiction, and various other addictions. His patients helped him to maintain and develop the Temple, either by direct involvement in the construction work or through sponsorship.
