Humayun's Tomb is one of the finest examples of Mughal architecture in India and a UNESCO World Heritage Site. Built in 1570 by Empress Bega Begum in memory of Mughal Emperor Humayun, it was the first grand garden-tomb on the Indian subcontinent and later inspired the design of the Taj Mahal. Constructed using red sandstone and white marble, the monument is surrounded by beautiful Charbagh-style gardens, water channels, and fountains. The complex also houses several other Mughal-era monuments, including Isa Khan's Tomb, Bu Halima's Garden, and Barber's Tomb. Known for its architectural elegance and historical significance, Humayun's Tomb is one of Delhi's most visited heritage attractions.
