In 1909 , Haifa became important to the Bahá 'í Faith when the remains of the Báb , founder of the Bábí Faith and forerunner of Bahá 'u'lláh in the Bahá 'í Faith , was moved from Acre to Haifa and interred in the shrine built on Mount Carmel . Bahá 'ís consider the shrine to be their second holiest place on Earth after the Shrine of Bahá 'u'lláh in Acre . Its precise location on Mount Carmel was shown by Bahá 'u'lláh himself to his eldest son , `Abdu 'l @-@ Bahá , in 1891 . `Abdu 'l @-@ Bahá planned the structure , which was designed and completed several years later by his grandson , Shoghi Effendi . In a separate room , the remains of `Abdu 'l @-@ Bahá was buried in November 1921 .
