The Constituent Assembly of India held its meetings in Constitution Hall, New Delhi, which is now known as the Central Hall of Parliament House. The Assembly never met in Calcutta, Bombay, or Madras.
The Constituent Assembly was formed in 1946 with the task of drafting a constitution for independent India. It held its first meeting on December 9, 1946, and its last meeting on January 26, 1950. The Assembly met in New Delhi for a total of 166 days over 11 sessions.
The Assembly's debates were recorded and published as the "Constituent Assembly Debates." These debates are an important source of information about the drafting of the Indian Constitution.
