A Mashriqu'l-Adhkár, Dawning-Place of the Mention of God, must have nine sides and nine entrances, symbolising approach from every direction, and a dome. Inside there is no altar, no pulpit, no image, no fixed seating arrangement of a hierarchical kind and no clergy. Only the scriptures of the world's religions may be read or chanted, unaccompanied by instruments, and no sermons are given. Each is intended eventually to be surrounded by dependencies — a school, a hospital, a hostel for travellers, a home for the aged — of which very few have been built. There are eight continental Houses of Worship: Wilmette in Illinois, Kampala, Sydney, Frankfurt, Panama City, Apia in Samoa, New Delhi and Santiago de Chile, together with a growing number of national and local ones. The Delhi temple, opened in 1986 and shaped as a lotus, is one of the most visited buildings in the world, receiving several million visitors a year, the overwhelming majority of whom are Hindu and are not there as Bahá'ís.
