Over the centuries, it has served as a school for law students, a venue for qualified attorneys, and residential chambers.
The buildings include a hall with 18th-century chambers and reception rooms, featuring notable architectural elements like 15th-century wooden bays, 16th-century linen fold wood panelling, and the only surviving crown posts in Greater London.
An adjacent distillery, owned by a Roman Catholic, Mr Langdale (who escaped), was set alight by rioters.
The Hall and other buildings were damaged and one of the officers of the Inn witnessed a "sturdy fellow" pumping up gin from the cellar which he proceeded to sell at a penny a mug to the thirsty onlookers of the fire.
The windows contain the armorial bearings of Principals of Barnard's Inn: The hall was renovated again in 1990, adding facilities for meetings and functions, ready to become the home of Gresham College.
The hero of Charles Dickens's novel Great Expectations, Pip, lodged in Barnard's Inn with Herbert Pocket for a number of years following his arrival in London, which would have been circa 1820.
