Views of the Taj Mahal from Mehtab Bagh. Shah Jehan established Mehtab Bagh as a garden from where to view the Taj in the moonlight. He planned his own mausoleum, the Black Marble version of the Taj Mahal, to be built at this spot. The foundations were laid, but the project was aborted by Aurangzeb, who imprisoned Shah Jehan in the Agra Fort.
