Fatehpur Sikri is a UNESCO World Heritage Site that offers a glimpse into the glorious past of the Mughal empire. Built by Emperor Akbar in the 16th century, this red sandstone city was his grand vision of a new capital, but was abandoned after only 14 years due to water scarcity. Today, you can explore the splendid palaces, courtyards, and mosques that showcase the fusion of Persian and Indian architecture. Don't miss the majestic Buland Darwaza, the highest gateway in India, and the white marble tomb of Sheikh Salim Chishti, the saint who blessed Akbar with a son.
