One of the fantastic projects completed by Baker was the Legislative Assembly building (Parliament House). Baker constructed it in the shape of a circular colosseum. Situated north of the secretariat buildings, the parliament has a red stone foundation, a cream stone middle story with 144 pillars, and a top story in plaster. It has a diameter of 570 feet and a low central dome, which is not visible from the ground level.
There are three semicircular halls inside the Parliament House. Two of them are richly wood-paneled legislative chambers, the Lok Sabha and Rajya Sabha. The third hall (an opulent chamber of princes) is the library and reading room with carved benches, coloured marble pillars and jaalis and gilded enamel shields of the princely states set into the wall.
The most important part of the House is the large circular central hall with its 90 ft. (28-m) dome. It was here that the Constitution of Independent India was drafted. It was in this hall, on August 15, 1947, India has declared an Independent Nation.
