Fatehpur Sikri, located near Agra in the state of Uttar Pradesh, India, is a UNESCO World Heritage Site known for its well-preserved Mughal architecture. It was founded by Emperor Akbar in the 16th century and served as the capital of the Mughal Empire from 1571 to 1585. The city was abandoned due to water supply issues, but its structures, including palaces, mosques, and courtyards, remain remarkably intact, showcasing the architectural brilliance of the Mughal era.
