Charbagh or Chahar Bagh is a Persian and Islamic quadrilateral garden layout based on the four gardens of Paradise mentioned in the Quran. The quadrilateral garden is divided by walkways or flowing water into four smaller parts. In Persian, "Chahar" means four, which corresponds to "Char", which means four in Urdu, while "bagh" means 'garden' in both Persian and Urdu.
Shah Jahan adapted the river-front garden in the layout of the Taj Mahal, the grandest architectural accomplishment of his reign. Here, the white marble mausoleum was placed on a terrace by the edge of the river and the garden was to its south.
