The London Skyline pictured from the Tower of London.
In the UK, especially in London, buildings are sometimes nicknamed after inanimate objects. In the image above, there is the 'walkie talkie', the 'cheese grater' and the 'gherkin'.
When I took my younger sister (from America) to London last month, I told her about these nicknames and she didn't know what a gherkin was. I explained that it's what she would call a pickle. She found this hilarious and now will send me messages weekly with pictures of pickles!
