The landmark administrative building of Kolkata, designed by Thomas Lyon in 1777. It originally served as the principal administrative office for writers (junior clerks) of the British East India Company (EIC). The building became famous for its involvement with three youngsters who dared to challenge the British rule in 1930. Since India's independence in 1947, it has housed the office of the Chief Minister, cabinet ministers and other senior officials.

A three-storey Italianate structure, consisting of floors covered by marble and Chunar sandstone. During its use as a currency office, the central hall contained the exchange counters for banknotes, gold, silver, and small change. It was converted into a modern art gallery on 11 January 2020.

Notable for its imposing high domed roof (rising over 220 ft) and tall Ionic-Corinthian pillars. It was built in 1868, at the site of the old Fort William, and has remained an important landmark of the city ever since.

Contains a heritage gallery.

A philatelic museum beside the GPO, housed in the ground floor of a red building. It is dedicated to the history of postal services and the contributions of runners, who delivered mail from one place to another.

It also has a wide collection of stamps and letters, along with a signature of Rabindranath Tagore on his Santiniketan passbook. There are also signatures of CV Raman and portraits of many other individuals who once worked for the Indian postal service.
