Short answers, pulled from the story.
Anarkali was a figure named in contemporary Western travelers' accounts from the Mughal period. According to legend, Emperor Jehangir built the tomb for her after Emperor Akbar suspected her of having relations with Prince Saleem, the name Jehangir bore before his reign. No independent historical confirmation of her existence has been found; the story is regarded as a mix of scholarly speculation and literary fictionalization.
Construction of the Tomb of Anarkali dates to either 1599 or 1615. It is considered one of the earliest Mughal tombs still in existence and one of the most significant buildings of the early Mughal period.
The Tomb of Anarkali currently serves as the Punjab Archives, located within the Punjab Civil Secretariat complex in Lahore, Pakistan. Public access to the building is limited.
The Tomb of Anarkali is octagonal in plan, with alternating side lengths of 44 feet and 30 feet, and semi-octagonal towers at each corner. It is topped by a double dome resting on eight arches, each measuring 12 feet 3 inches, making it one of the earlier Mughal examples of that dome form.
The white marble cenotaph is carved with the 99 names of Allah and a Persian couplet from the poet Saadi. The couplet reads: "Ah! could I behold the face of my beloved once more, I would give thanks unto my Creator until the day of resurrection."
British administrators converted the Tomb of Anarkali into clerical offices in 1847. By 1851 it had been turned into the Anglican St. James Church, which came to be regarded as Lahore's "Protestant Cathedral." The church congregation relocated in 1891, after which the building became the Punjab Record Office.
