Delhi has a long history, and has been an important political centre of India as the capital of several empires. Much of Delhi's ancient history finds no record and this may be regarded as a lost period of its history. Extensive coverage of Delhi's history begins with the onset of the Delhi Sultanate in the 12th century. Since then, Delhi has been the centre of a succession of mighty empires and powerful kingdoms, making Delhi one of the longest-serving capitals and one of the oldest inhabited cities in the world. Delhi is very famous It is considered to be a city built, destroyed and rebuilt several times, as outsiders who successfully invaded the Indian Subcontinent would ransack the existing capital city in Delhi, and those who came to conquer and stay would be so impressed by the city's strategic location as to make it their capital and rebuild it in their own way.
The India Gate is a war memorial located astride the Rajpath, on the eastern edge of the "ceremonial axis" of New Delhi, formerly called Kingsway. It stands as a memorial to 70,000 soldiers of the British Indian Army who died in between 1914–1921 in the First World War, in France, Flanders, Mesopotamia, Persia, East Africa, Gallipoli and elsewhere in the Near and the Far East, and the third Anglo-Afghan War. 13,300 servicemen's names, including some soldiers and officers from the United Kingdom, are inscribed on the gate.
Designed by Sir Edwin Lutyens, the gate evokes the architectural style of the triumphal arch such as the Arch of Constantine, in Rome, and is often compared to the Arc de Triomphe in Paris, and the Gateway of India in Mumbai.
Akshardham or Swaminarayan Akshardham complex is a Hindu temple, and a spiritual-cultural campus in Delhi, India.

The Red Fort is a historic fort in the city of Delhi in India, which served as the main residence of the Mughal Emperors. Every year on the Independence day of India, the Prime Minister hoists the Indian "tricolour flag" at the main gate of the fort and delivers a nationally broadcast speech from its ramparts. On 15 August 1947, the first Prime Minister of India Jawaharlal Nehru raised the Indian national flag above the Lahore Gate. On each subsequent Independence Day, the prime minister has raised the flag and given a speech that is broadcast nationally.
The Qutb Minar, also spelled as Qutub Minar, is a minaret and "victory tower" that forms part of the Qutb complex, a UNESCO World Heritage Site in the Mehrauli area of Delhi, India. Qutb Minar was 73-metres tall before the final, fifth section was added after 1369. The tower tapers, and has a 14.3 metres base diameter, reducing to 2.7 metres at the top of the peak. It contains a spiral staircase of 379 steps. Its closest comparator is the 62-metre all-brick Minaret of Jam in Afghanistan, of c.1190, a decade or so before the probable start of the Delhi tower.
The Lotus Temple, located in Delhi, India, is a Baháʼí House of Worship that was dedicated in December 1986. Notable for its flowerlike shape, it has become a prominent attraction in the city. Like all Bahá’í Houses of Worship, the Lotus Temple is open to all, regardless of religion or any other qualification. The building is composed of 27 free-standing marble-clad "petals" arranged in clusters of three to form nine sides, with nine doors opening onto a central hall with a height of slightly over 34.27 metres and a capacity of 2,500 people.
Jantar Mantar is located in the modern city of New Delhi. It consists of 13 architectural astronomy instruments. The site is one of five built by Maharaja Jai Singh II of Jaipur, from 1723 onwards, revising the calendar and astronomical tables. There is a plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was placed there in 1910 mistakenly dating the construction of the complex to the year 1710. Later research, though, suggests 1724 as the actual year of construction. Its height is 723 feet.
