Taj Mahal is regarded as one of the eight wonders of the world, and some Western historians have noted that its architectural beauty has never been beaten. The Taj Mahal is built entirely of marble. Its stunning architectural beauty is beyond adequate description, particularly at dawn and sunset. The Taj seems to glow in the light of the full moon. On a foggy morning, the visitors experience the Taj Mahal as if suspended when viewed from across the Jamuna river.
