Taj Mahal, Agra, India
From the out side, in the right light, the Taj Mahal is magical, looming like a mirage through its main gateway.

Inside, the tomb houses two false cenotaphs surrounded by an intricate marble screen. The actual caskets of Mumtaz Mahal and Shaah Jahaan are stored in a relatively plain crypt beneath the inner chamber.
