Top 10 Places to Visit in Delhi | Delhi's Top Tourist Attractions.

Delhi's most famous monument, the Red Fort, stands as a powerful reminder of the Mughal emperors who ruled India. Its walls, which stretch for over two kilometers (1.2 miles), were built in 1638 to keep out invaders. However, they failed to stop the fort being captured by the Sikhs and the British. To take your imagination back to the ancient era, a one hour sound and light show of the fort's history is held each evening.

Chandni Chowk, the main street of old Delhi, is a shocking contrast to the wide, orderly streets of New Delhi. Cars, cycle rickshaws, hand-pulled carts, pedestrians, and animals all compete for space. It's chaotic, crumbling and congested, but completely captivating as well. As one of the oldest and busiest markets in India, its narrow winding lanes are full of inexpensive jewelry, fabrics, and electronics. For the more adventurous, Chandni Chowk is an excellent place to come to sample some of Delhi's street food. The renowned Karim Hotel, a Delhi dining institution, is also located there.

• Location: Old Delhi, near the Red Fort and Jama Masjid. 

If you think Humayun's Tomb looks a bit like the Taj Mahal in Agra, that's because it was the inspiration for the Taj Mahal's creation.

The tomb is part of a greater complex that's set amongst beautiful gardens.

Qutab Minar, the tallest brick minaret in the world, is an incredible example of early Indo–Islamic architecture. It was built in 1206, but the reason remains a mystery. Some believe that it was made to signify victory and the beginning of Muslim rule in India, while others say it was used to call the faithful to prayer. The tower has five distinct stories, and is covered with intricate carvings and verses from the holy Quran. There are also a number of other historic monuments on the site.
