The Taj Mahal (/ˌtɑːdʒ məˈhɑːl, ˌtɑːʒ-/; lit. 'Crown of the Palace')[4][5][6] is an ivory-white marble mausoleum on the right bank of the river Yamuna in Agra, Uttar Pradesh, India. It was commissioned in 1631 by the fifth Mughal emperor, Shah Jahan (r. 1628–1658) to house the tomb of his beloved wife, Mumtaz Mahal; it also houses the tomb of Shah Jahan himself. The tomb is the centrepiece of a 17-hectare (42-acre) complex, which includes a mosque and a guest house, and is set in formal gardens bounded on three sides by a crenellated wall.

The Agra Fort (Qila Agra) is a historical fort in the city of Agra, and also known as Agra's Red Fort. Mughal emperor Humayun was crowned at this fort. It was later renovated by the Mughal emperor Akbar from 1565 and the present-day structure was completed in 1573. It served as the main residence of the rulers of the Mughal dynasty until 1638, when the capital was shifted from Agra to Delhi. It was also known as the "Lal-Qila" or "Qila-i-Akbari".[1] Before being captured by the British, the last Indian rulers to have occupied it were the Marathas. In 1983, the Agra fort was inscribed as a UNESCO World Heritage Site because of its importance during the Mughal Dynasty.[2] It is about 2.5 kilometers (1.6 mi) northwest of its more famous sister monument, the Taj Mahal. The fort can be more accurately described as a walled city. It was later renovated by Shah Jahan.

Tomb of I'timād-ud-Daulah (I'timād-ud-Daulah Maqbara) is a Mughal mausoleum in the city of Agra in the Indian state of Uttar Pradesh. Often described as a "jewel box", sometimes called the "Bachcha Taj" or the "Baby Taj", the tomb of I'timād-ud-Daulah is often regarded as a draft of the Taj 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 Taj Mahal.
