London's architectural heritage involves many architectural styles from different historical periods. London's architectural eclecticism stems from its long history, continual redevelopment, destruction by the Great Fire of London and The Blitz, and state recognition of private property rights which have limited large scale state planning. This sets London apart from other European capitals such as Paris and Rome which are more architecturally homogeneous.[1] London's architecture ranges from the Romanesque central keep of The Tower of London, the great Gothic church of Westminster Abbey, the Palladian royal residence Queen's House, Christopher Wren's Baroque masterpiece St Paul's Cathedral, the High Victorian Gothic of The Palace of Westminster, the industrial Art Deco of Battersea Power Station, the post-war Modernism of The Barbican Estate and the Postmodern skyscraper 30 St Mary Axe 'The Gherkin'.
