154. Raise up and exalt the two Houses in the Twin Hallowed Spots, and the other sites wherein the throne of your Lord ... hath been established. # 133Baha'u'llah identifies the "two Houses" as His House in Baghdad, designated by Him as the "Most Great House", and the House of the Bab in Shiraz, both of which have been ordained by Him as sites of pilgrimage. (See Q and A 29, 32 and note 54.)
Shoghi Effendi explained that "the other sites wherein the throne of your Lord ... hath been established" refers to those places where the Person of the Manifestation of God has resided. Baha'u'llah states that "the people of the areas where these are situated may choose to preserve either each house" wherein He resided, "or one of them" (Q and A 32). Baha'i institutions have identified, documented, and where possible, acquired and restored a number of the historical sites associated with the Twin Manifestations.
