As the seat of the Government of West Bengal, Kolkata is home to not only the offices of the local governing agencies, but also the West Bengal Legislative Assembly; the state secretariat, which is housed in the Writers' Building; and the Calcutta High Court. Most government establishments and institutions are housed in the centre of the city in B. B. D. Bagh (formerly known as Dalhousie Square). The Calcutta High Court is the oldest High Court in India.
