London

London's architecture spans nearly a thousand years in a single skyline, medieval and Georgian survivors sitting alongside Victorian civic buildings and a growing cluster of contemporary towers like the Shard and 22 Bishopsgate. Planning is shaped by strict height controls around protected sightlines to St Paul's, which has pushed much of the recent high-rise development into clusters like the City and Canary Wharf, while conservation areas keep large parts of the historic fabric intact.
