The Shrine of the Báb is a structure on the slopes of Mount Carmel in Haifa, Israel, where the remains of the Báb, founder of the Bábí Faith and forerunner of Baháʼu'lláh in the Baháʼí Faith, are buried; it is considered to be the second holiest place on Earth for Baháʼís, after the Shrine of Baháʼu'lláh in Acre. Its precise location on Mount Carmel was designated by Baháʼu'lláh himself to his eldest son, ʻAbdu'l-Bahá, in 1891. ʻAbdu'l-Bahá planned the structure, which was designed and completed several years later by his grandson, Shoghi Effendi. Crowning the design, as anticipated by ʻAbdu'l-Bahá, is a dome, which is set on an 18-windowed drum. That, in turn, is mounted on an octagon, a feature suggested by Shoghi Effendi. An arcade surrounds the stone edifice. A restoration project of the exterior and interior of the shrine started in 2008 and was completed in April 2011. History First mausoleum Bahá'u'lláh arrived in the Haifa-Akka region as a prisoner of the Ottoman Empire in the same year as the first German Templer colony in Palestine was founded in Haifa. Years later, after his release from strict confinement, he visited the Templer Colony on Mount Carmel several times and wrote a letter to Georg David Hardegg, the co-founder of the Templer movement. He subsequently asked his son, ‘Abdu’l-Baha, to build, on the alignment of the Templer Colony road (Carmel Avenue) with the shrine to the forerunner of the religion, known as "the Bab," halfway up the mountain. The conjunction of the Templer buildings and the Shrine have become the most significant landmark in the modern city of Haifa. The remains of the Báb were buried on March 21, 1909 in a six-room mausoleum made of local stone. In a separate room, the remains of ʻAbdu'l-Bahá were buried in November 1921. In 1929 three rooms were added to the mausoleum. Final shrine In 1949 the first threshold stone of the superstructure was laid by Shoghi Effendi. The construction was completed over the mausoleum in 1953 and was entirely paid for by Baháʼís around the world. The architect was William Sutherland Maxwell, a Canadian Baháʼí 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 Baveno rose granite colonnade, Oriental-style Chiampo stone arches, and
