Admire its magnificence, examine the minute elements of its architecture, and enjoy the calm atmosphere while you watch people making their prayers.

Proceed to the adjacent Red Fort, a UNESCO World Heritage Site and a famous representation of India's lengthy past.

Stop for lunch at a neighboring restaurant and sample some of the best street food in the area or true Mughlai cuisine.

After lunch, travel to Humayun's Tomb, a magnificent example of Mughal architecture and another UNESCO World Heritage Site. Emperor Humayun's wife, Empress Bega Begum, commissioned the construction of this mausoleum in the 16th century, which is renowned for its exquisite Persian-inspired architecture and verdant gardens. Take some time to explore the complex's exquisite marble work, calming water features, and peaceful atmosphere.

Visit Qutub Minar, another UNESCO World Heritage Site and the world's highest brick minaret, to round off your day. The minaret, which was constructed in the twelfth century by Qutb-ud-din Aibak, the first king of the Delhi Sultanate, is evidence of the city's rich architectural history. As the day draws to an end, you have the option of returning to your lodging or taking in some shopping and dining at the local Delhi marketplaces and streets.
