This vault would be opened only once in a year on the anniversary day. The central chamber is surrounded by eight smaller ones. The light in the chambers is admitted through finely latticed marble screens. The echo in the central chamber under the huge soaring central dome is a really marvel in the Direct Flights To Lucknow. A sound softly produced is echoed in an endless harmony. The superb inlay work of the Taj involving such precious and semi-precious stones as jade, jasper, crystal, turquoise, lapis lazuli, sapphire, coral, onyx and amethyst, glows in the light filtered into through the finely cut marble screens.
