Who built bahai temple?
Inception of the Baha’i Faith was in the 19th Century, so no Baha’i temple would be found in the Old Testament. There is a Baha’i mother temple on each continent, open to the followers of ALL religions for prayer/meditation, and there have been different architects and different builders. The only architectural prerequisite is that the temple must be nine-sided because of the association of 9 with perfection, unity and ‘Baha’ (ie., ‘Glory’).
