Above is a photo of the House of the Bab in Shiraz where He declared His Mission on May 22nd-23rd, 1844 CE (1260 AH). The House was destroyed and levelled for a parking lot for a Mosque in 1979 but photos tell us what it was like..Actually the House has been destroyed before:
The first time was in 1942 when it was raided and damaged by fire,
after which the Baha`is raised funds to restore it to its original condition.
The second was in 1955 when `uncontrollable mobs' stormed the building, looting anything of value and reducing part of it to rubble.
So we remember the House of the Bab especially on this Holy Day of the Declaration of the Bab:

On May 23, 1844, the Bab ("gate" in Arabic) announced that He was the bearer of a long-promised Divine Revelation destined to transform the spiritual life of the human race.
His role, He said, was to be the portal through which the universally anticipated Revelation of God would appear in the form of another Messenger. This Messenger from God would be far greater: He would usher in the age of peace and justice promised in Islam, Judaism, Christianity and all the other world religions.
The Bab referred to the Messenger as "Him Whom God shall make manifest" and said, "No words of Mine can adequately describe Him nor. . . do justice to His Cause."
That Messenger was Baha'u'llah.
On May 23, Baha'is celebrated the anniversary of the Declaration of the Bab, who, after His announcement, was arrested, beaten and imprisoned. On July 9, 1850, He was executed in the public square of the town of Tabriz.
The Declaration of the Bab is one of nine holy days on which Baha'is suspend work and school.
Prominent 19th century French writer A.L.M. Nicolas wrote that the Bab's life "is one of the most magnificent examples of courage which it has been the privilege of mankind to behold."
