Situated in midst of the beautiful Indo-Islamic structures of the Qutub Minar complex, stands the elegant Alai Darwaza (gate). By the time it was finished in 1311, Indian workmen had mastered the art of constructing a dome. Through the system of a series of arched brackets, the square chamber was converted into a octagon and then a circle, and the dome was mounted on it. This celebrated gate is built of red sandstone with arched openings on all sides. It is full of scripts carved with ancient inscriptions and has many other decorative details in white marble.
