The Red Fort (known as the Lal Qila in Hindi) is an old fort complex located in Delhi. It was constructed by the Mughal emperor Shah Jahan, who also constructed the world-famous Taj Mahal, in the 17th century. The fort served as the residence of the Mughal emperor, his acolytes and their families. It was also the place from where the emperors ran their vast empire. Currently designated as a UNESCO World Heritage, the fort complex serves as a tourist spot and is a powerful symbol of the Indian Republic. The prime minister addresses the nation from this complex on the Independence Day each year. Today the Red Fort is seen as the symbol of the seat of power of government of India. The Red Fort is heavily guarded and has been a subject of a terror attack in 22 December 2000 by Lashkar-e-Taiba (one of the most militant terror outfit in South Asia).
