There was a lot of religious strife, which still persists in Ayodhya in the north of Varanasi. Medieval rulers and emperors have left impressive monuments like palaces, forts, temples, and mausoleums, whose external and interior magnificence reminds of the affluence of those times.

With its many arches and no sculptures to adorn it, the temple resembles a mosque. The Jagat Kishore temple and the Madan Mohona temple are among the other Hindu architecture of Vrindavan. In Varanasi there is an amalgamation of Rajput, Hindu and Muslim architecture.

The Mughals who ruled over most of India, made Agra and Delhi their capital and the third Mughal emperor, Akbar, tried to bring harmony between the two religions. In architecture too, he tried to blend practical sciences of Hinduism with the Islamic architecture styles. He incorporated the pillar and beam construction technology of the Hindu architectural style and developed his own unique style of architecture. This style is reflected in his tomb in Sikandra, outside Agra and in the new city that he built, called Fatehpur Sikri. The Mughal gardens constructed by Babur in Agra are an outstanding example of Islamic architecture of Uttar Pradesh. Red sandstones and marbles were the main elements of Islamic architecture.
