Standing in contrast to the gleaming white marble of the Taj Mahal, the red sandstone walls of the nearby Red Fort are a testament to the strength and power of the Mughal rulers. Dating back to the 16th century, this UNESCO World Heritage Site is a palatial warren of courtyards, pavilions and grand rooms. Marvel at the stories of the Mughal empire as you explore the vast fort, including the tower where Shah Jehan was imprisoned and spent his final years gazing out at the Taj Mahal, the resting place of his beloved Mumtaz.
