It is a small town located on national highway toconnecting Delhi to Kolkata. The town is believed to be named after Mirza Ghiyas Beg the I'timād-ud-Daulah, a Mughal official, father of Nur Jahan and grandfather of Mumtaz Mahal.

Itmad-ud-Daula's Tomb (Urdu: اعتماد الدولہ کا مقبرہ‎, I'timād-ud-Daulah kā Maqbara) is a Mughal mausoleum in the city of Agra in the Indian state of Uttar Pradesh. Often described as 'jewel box', sometimes called the 'Baby Tāj', the tomb of I'timād-ud-Daulah is often regarded as a draft of the Tāj Mahal.
Along with the main building, the structure consists of numerous outbuildings and gardens. The tomb, built between 1622 and 1628 represents a transition between the first phase of monumental Mughal architecture - primarily built from red sandstone with marble decorations, as in Humayun's Tomb in Delhi and Akbar's tomb in Sikandra - to its second phase, based on white marble and pietra dura inlay, most elegantly realized in the Tāj Mahal.
The mausoleum was commissioned by Nūr Jahān, the wife of Jahangir, for her father Mirzā Ghiyās Beg, originally a Persian Amir in exile .[1] who had been given the title of I'timād-ud-Daulah (pillar of the state). Mirzā Ghiyās Beg was also the grandfather of Mumtāz Mahāl (originally named Arjūmand Bāno, daughter of Asaf Khān), the wife of the emperor Shāh Jahān, responsible for the building of the Tāj Mahal.

Located on the left bank of the Yamuna river, the mausoleum is set in a large cruciform garden criss-crossed by water courses and walkways. The mausoleum itself covers about twenty-three meters square, and is built on a base about fifty meters square and about one meter high. On each corner are hexagonal towers, about thirteen meters tall.
The walls are white marble from Rajasthan encrusted with semi-precious stone decorations - cornelian, jasper, lapis lazuli, onyx, and topaz formed into images of cypress trees and wine bottles, or more elaborate decorations like cut fruit or vases containing bouquets. Light penetrates to the interior through delicate jālī screens of intricately carved white marble.
Many of Nūr Jahān's relatives are interred in the mausoleum. The only asymmetrical element of the entire complex is that the cenotaphs of her father and mother have been set side-by-side, a formation replicated in the Tāj Mahal
