The layout of the Taj Mahal has symbolic meaning; its main gate symbolizes a barrier between the outside world and the purity and serenity of the inside world. It is constructed of white marble, the color of purity. The use of water in the garden also symbolizes purity, emphasizing the belief that the Taj Mahal is a holy site. As one enters the heart of the mausoleum, Islamic prayers can be read above the doorway, which are recited before a person of the Islamic faith dies. Same Day Agra Tour by Car gives you an opportunity to visit this wonderful Monument.
