It seems there might be a misunderstanding in your question. The "Baby Taj" is a common nickname for the Itimad-ud-Daulah's Tomb, a Mughal mausoleum in Agra, India, often described as a draft of the Taj Mahal. It is a historically and architecturally significant monument in India. The Itimad-ud-Daulah is a white marble structure known for its exquisite inlay work and delicate carvings. It features a central tomb surrounded by a charbagh (a traditional Persian-style garden with four quadrants), which is a common feature in Mughal architecture. The mausoleum is adorned with intricate floral motifs, calligraphy, and geometric designs. The use of precious and semi-precious stones for inlay work adds to its aesthetic beauty.
