India's religious tolerance has made lots of religion flourish. The religious centers of Islam are not only a place of worship, but a center of learning too. There are tombs such as Taj Mahal that showcases the depth of undying love and Mughal Emperor Humayun's Tomb, which is considered the most perfectly planned octagonal building in the history of Indian Architecture.

Agra and Fatehpur Sikri are not mere rich legacies of Mughal History, they are the finest examples of architecture, which combined both Hindu and Muslim elements in it. The remains of seven cities in Delhi include the remnants of Shahjhanabad and Qutub Minar, which are worth a visit. Lucknow and Hyderabad's Nawabi legacy is still lurking in the monuments such a Bada Imambara and Charminar.
