Is the juxtaposition of historical and modern elements like in the photo below:
On the left is the nearby architectural icon The Shard, a modern skyscraper that has helped define London's skyline today. On the right, with its modest, traditional architecture, is one of London's surviving structures that reflect the city's past - Wharfinger Cottage. The cottage itself has been here for at least 200 years, although it has probably been renovated or restored at some point, and originally it was the home of the Controller of the Tower Wharf, known as the Wharfinger.
The Wharf used to be a busy dockside with weapons, gunpowder and other military supplies being shipped to and from the Tower, where they were stored and secured under the Wharfinger’s supervision.
Nowadays, I think Wharfinger Cottage is a private residence so who the current occupants are is anyone's guess.
And if you turn around you're met with the Tower of London itself:
This is looking at the western side of the Tower of London from the northern side of the River Thames. Just along the northern bank and walking eastward to Tower Bridge, ...
And then the view from the southern side looking over the River Thames towards The Tower of London. (Wharfinger Cottage now at the foot of the fat skyscraper on the left - you have to zoom in to see it).
