Red Fort
Netaji Subhash Marg, Old Delhi, Delhi, India

Red Fort is one of Delhi’s defining monuments: the palace-fort of Shah Jahan’s 17th-century capital of Shahjahanabad and today a UNESCO World Heritage property. Official tourism material identifies it as the historic heart of Mughal power in Old Delhi, while UNESCO’s listing notes the fusion of Persian, Timurid and Hindu architectural traditions across the wider Red Fort Complex. Entering through Lahori Gate, visitors move from the busy approach into a sequence of ceremonial and residential spaces that still convey the scale of an imperial court. Key points inside include Chhatta Chowk, Naubat Khana, Diwan-i-Am, Diwan-i-Khas, Rang Mahal, Khas Mahal, Hammam and the Mumtaz Mahal museum setting. This ranking reflects both historical weight and practical usefulness on a first Delhi trip: the fort places you directly within Old Delhi’s dense urban fabric while remaining a self-contained monument visit. Incredible India currently lists visitor hours as 9.30 am to 4.30 pm, closed Mondays, and also notes the evening Jai Hind sound-and-light show on operating days. Expect airport-style security screening, controlled entry and substantial walking across open grounds. Its location on Netaji Subhash Marg keeps it firmly inside the National Capital Territory and makes it easy to combine with nearby sights such as Jama Masjid and Chandni Chowk.
