Parts of the current building date from 1411 and it is the only stone building not belonging to the Church to have survived the Great Fire of London and the ages. It is believed be on the site of an earlier Guildhall, and has large medivial crypts underneath. During the Roman period it was the site of an ampitheatre, the largest in Britannia.
The day-to-day administration of the Corporation of London has long since moved elsewhere, but the building is still used for ceremonial purposes such as banquets.
