Beneath it an enclosure of marble trellis-work surrounds the tomb of the princess and of her husband, the Emperor.

Each corner of the mausoleum is covered by a similar though much smaller dome erected on a pediment pierced with graceful Saracenic arches.

Light is admitted into the interior through a double screen of pierced marble, which tempers the glare of an Indian sky while its whiteness prevents the mellow effect from degenerating into gloom.

The internal decorations consist of inlaid work in precious stones, such as agate, jasper, etc., with which every squandril or salient point in the architecture is richly fretted.

Brown and violet marble is also freely employed in wreaths, scrolls, and lintels to relieve the monotony of white wall.
