A direct consequence of Delhi's rich history is its magnificent monuments. The Old City is the site where the Mughals and the Turkic rulers constructed several architectural marvels like the Jama Masjid and Lal Qila while the Birla Mandir and Chattarpur Temple represent a blend of North and South Indian architectural styles. The Archaeological Survey of India recognises more than 172 monuments in Delhi as national heritage sites. Two World Heritage Sites, the 72.5 meters tall Qutab Minar and Humayun's Tomb, are located in Delhi. Other famous monuments include the India Gate,the Jantar Mantar, an 18th century astronomical observatory, and the Purana Qila, a 16th century fortress.

The Lotus Temple, a symbol of Delhi's religious tolerance and unity, is the most visited edifice in the world with more 50 million visitors annually. Delhi offers a glimpse of India's religious diversity. The largest mosque in India, the Jama Masjid and one of the most visited Vaishnavite temples in the world, the Birla Mandir, are located in Delhi. New Delhi, a spacious, well-designed district of Delhi, houses several government buildings and official residences reminiscent of the British colonial architecture. Important structures include the Rashtrapati Bhavan, the Secretariat, the Rajpath, the Parliament of India and the Vijay Chowk.

Delhi is a noted centre of performing arts. Several theatres and cinema halls are located here. However, the cinema industry in the city is virtually non-existent. The India Habitat Centre provides a physical environment which would serve as a catalyst for a synergetic relationship between individuals and institutions working in diverse habitat related areas.

Historically, Delhi has always remained an important trading center in northern India. Chandni Chowk, a three century old shopping area, is perhaps the most famous commercial area in India. Connaught Place, a major commercial center in the heart of New Delhi, is not only a shopper's paradise but also offers a glimpse of Colonial-era architecture.
