Itmad-ud-Daulah, often referred to as the "Baby Taj," is a beautiful Mughal mausoleum located in Agra, India. Built between 1622 and 1628, it was commissioned by Nur Jahan, the wife of Emperor Jahangir, for her father Mirza Ghiyas Beg, who was given the title "Itmad-ud-Daulah," meaning "Pillar of the State." The mausoleum marks an important departure from traditional Mughal architecture, as it was the first in India to be constructed entirely out of white marble, adorned with intricate inlay work. It features delicate carvings, floral patterns, and lattice marble screens, showcasing a blend of Persian and Mughal influences. The monument stands on the banks of the Yamuna River, surrounded by lush gardens, and is often considered a precursor to the more famous Taj Mahal. Its architectural elegance and intricate craftsmanship make Itmad-ud-Daulah an essential part of Agra's rich historical heritage.
