Sumner Buildings Great Guildford Street London 2 2 2018

The City of London is known as the square mile, as it is in a very compact central London location. It is packed with offices, churches, stations and official buildings. It has for several centuries been unable to house all the workers it needs in its own boundaries. These blocks of flats are across the river Thames, in Southwark. The Shard can be seen in the background.
