The Red Fort (Lal Qila) and the Jama Masjid in Delhi were built by:

Shah Jahan (ruled 1628-1658) was the fifth Mughal emperor. His reign is called the "Golden Age of Mughal architecture" because of the many magnificent buildings he constructed, mostly using white marble.

In 1638, Shah Jahan decided to shift his capital from Agra to Delhi. He founded a new city called Shahjahanabad (now Old Delhi). Its centrepiece was the Red Fort, built of red sandstone between 1638 and 1648. It was designed by the architect Ustad Ahmad Lahauri, who is also associated with the Taj Mahal. The fort was originally called "Qila-e-Mubarak" (the blessed fort). Important structures inside it include:

Diwan-i-Am (Hall of Public Audience).

Diwan-i-Khas (Hall of Private Audience), where the famous Peacock Throne was kept. A Persian couplet on its walls reads: "If there is paradise on earth, it is this, it is this, it is this."

Rang Mahal, Moti Masjid (added by Aurangzeb) and the Nahr-i-Bihisht (Stream of Paradise).

The Peacock Throne was carried away by Nadir Shah of Persia in 1739. The Red Fort was declared a UNESCO World Heritage Site in 2007. Since 15 August 1947, when Jawaharlal Nehru hoisted the national flag there, the Prime Minister has addressed the nation from its ramparts every Independence Day.

The Jama Masjid (Masjid-i-Jahan Numa), built between 1650 and 1656, is one of the largest mosques in India. It is built of red sandstone and white marble.

Shah Jahan's other famous buildings include the Taj Mahal at Agra (built in memory of his wife Mumtaz Mahal), the Moti Masjid in the Agra Fort and the Shalimar Bagh in Lahore. He was deposed and imprisoned in the Agra Fort by his son Aurangzeb in 1658 and died there in 1666.
