Itmad-ud-Daula is a stunning Mughal mausoleum located in the historic city of Agra in Uttar Pradesh, India, situated on the eastern bank of the Yamuna River near other famous sites like the Taj Mahal and Agra Fort. Built between **1622 and 1628 by Empress Nur Jahan in memory of her father, Mirza Ghiyas Beg (Itmad-ud-Daula), this exquisite tomb is often called the “Baby Taj” or “jewel box” for its elegant design and intricate marble inlay work that foreshadows the architectural brilliance of the later Taj Mahal. Constructed entirely from white marble with delicate pietra dura (semi-precious stone inlay) and set within a serene Charbagh garden, Itmad-ud-Daula’s Tomb represents a key transitional moment in Mughal architecture and is a must-visit heritage attraction for history lovers exploring Uttar Pradesh’s rich cultural landscape.
