Agra Fort

Before the Taj, there was Agra Fort — the great red-sandstone stronghold that served as the main residence of the Mughal emperors for generations. Behind its massive double walls lies a city of palaces, mosques, audience halls and gardens blending red sandstone with delicate white marble.

It's also a place of poignant history: it was here that Shah Jahan, who built the Taj, spent his final years imprisoned by his own son, gazing out at his wife's tomb across the river. A UNESCO World Heritage Site, it's the perfect companion to a Taj visit.
