This history of the buildings of the Tower of London - one of England's most famous and popular tourist sites - shows how the monument has changed over the centuries. The author, who has himself undertaken detailed excavations in the Tower, traces the development of the fortifications and the evolution of the palatial complex. He looks at the numerous functions the buildings of the Tower have been put to fortress, armoury, palace, prison, mint and even zoo - and the adaptations made to house them all.
