bahá'u'lláh decreed pilgrimage in the kitáb-i-aqdas to two places: the house of bahá'u'lláh in baghdad, iraq and the house of the báb in shiraz, iran. while these major pilgrimages were later replaced (at least in terms of religious significance) by `abdu'l-bahá, many bahá'ís still flocked to bahá'u'lláh's home for pilgrimage until the house was confiscated by muslim authorities hostile to the bahá'í faith in 1922. it has yet to be returned to the bahá'í community. the house of the báb was completely destroyed by iranian muslims during a state-sponsored persecution of bahá'ís. a road and mosque were built over the house and a telephone pole now marks the spot where the báb proclaimed his prophethood. the city of baghdad also includes the garden of ridván, which shares the same name as – though is distinct from – the garden of ridván in acre.
