Humayun’s Tomb is one of Delhi’s most beautiful monuments, a magnificent 16th-century Mughal mausoleum and UNESCO World Heritage Site that inspired the design of the Taj Mahal. Set in formal charbagh gardens, its grand red-sandstone and white-marble structure, with soaring arches and a great dome, is a masterpiece of early Mughal architecture. A ticketed visit offers a serene and stunning escape from the city bustle, and the tomb’s harmony and beauty make it an essential and rewarding sight for anyone exploring the capital.
