“It is the principal reason behind the clustering of skyscrapers in only certain parts of the Square Mile, aka the City of London. Generally, buildings nearer the cathedral are lower (otherwise you end up with something like this.) One skyscraper, currently under construction, is the Leadenhall Building, also known as the Cheesegrater. It “leans back” from the road, as it increases in height, in order to minimise its impact on the background of the view of St Paul’s Cathedral from Fleet Street – not apparently defined as a protected view, but nonetheless a classic one.”
