The Red Fort, also known as the "Lal Qila," is a historic fort in Delhi, India. It was built by the Mughal Emperor Shah Jahan between 1638 and 1648 and served as the main residence of the Mughal emperors until 1857. The Red Fort is a UNESCO World Heritage Site and is one of Delhi's most famous landmarks.

The fort is made of red sandstone and is known for its stunning architecture, intricate carvings, and intricate lattice work known as "jaali." The fort's walls are over 33 meters high and 1.5 km long, and the fort has several gates, including the Lahori Gate, which is the main entrance. Inside the fort, there are several important structures, including the Diwan-i-Aam, the Diwan-i-Khas, the Moti Masjid, the Hayat Bakhsh Bagh, and the Khas Mahal.

The Red Fort is an important symbol of India's independence, as it was from its ramparts that the first Prime Minister of India, Jawaharlal Nehru, announced India's independence from British rule in 1947. Today, the Red Fort is a popular tourist attraction and is open to the public for visits and cultural events.
