(a) The monument is the Taj Mahal. Originally, it was surrounded by a dense garden with many ornamental and fruit trees — a particular style of garden cultivated by the Mughals.
(b) The disadvantage of the original garden layout was that the dense garden blocked the full view of the Taj Mahal.
(c) Today, the Taj Mahal is surrounded by colonial-style gardens. This style was introduced by the British, who preferred fewer trees and expansive lawns, making it possible to see the full structure of the monument.
(d) The Taj Mahal is made of pure white marble and decorated with semi-precious stones and lace-like screens. It is an octagonal monument with a splendid dome and four slender minarets, set in a beautiful garden. It was built on a rectangular grid, with Ustad Ahmad Lahori as its chief architect, and the calligrapher Amanat Khan worked on the marble inlaid with Koranic texts.
