Q: Passage: The Company's headquarters in London, from which much of India was governed, was East India House in Leadenhall Street. After occupying premises in Philpot Lane from 1600 to 1621; in Crosby House, Bishopsgate, from 1621 to 1638; and in Leadenhall Street from 1638 to 1648, the Company moved into Craven House, an Elizabethan mansion in Leadenhall Street. The building had become known as East India House by 1661. It was completely rebuilt and enlarged in 17269; and further significantly remodelled and expanded in 17961800. It was finally vacated in 1860 and demolished in 186162. The site is now occupied by the Lloyd's building.
