India’s largest city, Delhi, has been one of the country’s commercial and economic hubs for centuries and, as a result, is incredibly rich in culture and history. Made up of the ancient walled city of Old Delhi and the more modern sector, New Delhi, the city encompasses a staggering array of beautiful architecture, notable monuments and age-old temples, including three UNESCO World Heritage Sites – the Red Fort, Qutab Minar and Humayun's Tomb. Other key attractions include the 17th century Chandni Chowk marketplace – still one of the city’s most popular retail centres today, particularly for jewellery and traditional Indian saris; the iconic Bahà’i Lotus Temple – an award-winning architectural gem; and the Jama Masjid, India’s largest mosque.
