The fort was first mentioned in Alexander the Great's war records; it predates the birth of Christ.
The Kangra Fort was built by the Royal family of Kangra (The Katoch Dynasty), which traces its origins to the ancient Trigarta Kingdom, mentioned in the Mahabharata. It is the largest fort in the Himalayas and probably the oldest dated fort in India.
The entrance to the fort is through a small courtyard enclosed between two gates. From here a long and narrow passage leads up to the top of the fort, through the Ahani and Amiri Darwaza (gate). About 500 feet from the outer gate the passage turns round at a very sharp angle and passes through the Jehangiri Darwaza.
