The Belvedere Estate consists of Belvedere House and the 30-acre (12 ha) grounds surrounding it. It is located in Alipore, near the zoo, in Kolkata. In 1858, after the Governor-General moved out, the Lieutenant-Governor of Bengal took up residence in Belvedere House. When the capital moved from Kolkata to Delhi in 1911, the Lieutenant-Governor of Bengal, who had hitherto resided in Belvedere House, was upgraded to a full governor and transferred to Government House. Belvedere House has been the home of the National Library of India since 1948.
