The Temple of All Religions is a cascade of buildings, combining various styles of buildings of different cultures and religions into one. This is the only place in the world where you can marvel at the Orthodox and Catholic churches, the Muslim mosque, the Jewish synagogue and the Buddhist temple harmoniously coexisting all as one building. The temple is decorated with all the iconic elements of world religions, as well as symbols of extinct civilizations. Visitors are invited to visit the rooms of Jesus Christ, Buddha, the Catholic Hall, the Egyptian Hall, the theatre hall, the picture gallery, and the tea room. The unique temple can be clearly seen from ships sailing along the Volga River, as well as from the windows of the nearby passing trains. https://visit-tatarstan.com/en/places/religion/hram_vseh_religij/
