Agra has many historical sites to offer besides the iconic Taj Mahal. One of them is the Agra Fort, which is an example of Mughal architecture and served as a residence for emperors for over 200 years. Another site worth visiting is the Tomb of Itimad-ud-Daula, also known as "Baby Taj", a beautiful mausoleum built in memory of Nur Jahan's father. Finally, Fatehpur Sikri, an abandoned city near Agra, shows the grandeur and vision of the Mughal Empire.
