The architect of the Shrine of the Bab was William Sutherland Maxwell, a Canadian Baha'i who was a Beaux-Arts architect and the father-in-law of Shoghi Effendi. Shoghi Effendi provided overall guidance, including in the use of Western and Eastern styles, but left the artistic details to Maxwell. Maxwell's design of the Rose Baveno granite colonnade, Oriental-style Chiampo stone arches, and golden dome is meant to harmonize Eastern and Western proportions and style.
