Tughlaqabad Fort is a historic fort located in Delhi, India. Built in the 14th century by Ghiyas-ud-din Tughlaq, the founder of the Tughlaq dynasty, it served as a defensive structure and a royal residence. The fort is known for its massive walls, impressive gates, and strategic location on a rocky hill. The fort covers an area of about 6.5 kilometers and features several structures, including a palace, a mosque, and a water reservoir. Despite its grandeur, the fort was abandoned shortly after its construction due to various reasons, including water scarcity. Today, it stands as a popular tourist attraction and a reminder of Delhi's rich history.
