Royal Palace of Agra

It seems there might be some confusion. The Royal Palace of Agra is not a widely recognized historical site. Perhaps you are referring to the Agra Fort or the Taj Mahal? The Agra Fort is a massive red sandstone fortress built by Mughal emperors, serving as a royal residence and military fortification, featuring grand halls, gardens, and palaces. The Taj Mahal, while often called a palace, is primarily a tomb built by Emperor Shah Jahan. If you meant the Taj Mahal or Agra Fort, I can provide details on those. Please clarify.
