Built in 1639, the sandstone Red Fort is a magnificent piece of architecture. Within its wall are beautiful gardens, palaces and halls. Mughal Emperors made it their home for around 200 years. In recent years, the Red Fort’s significance has not been diminished, either. Keeping with tradition the Prime Minister of India, Narendra Modi, delivers his annual Independence Day speech at the Fort. In 2007, the Fort was declared a UNESCO World Heritage Site.
