The Gherkin plays a small, but significant role in Thor: The Dark World, as it is another building that Thor and Malekith crash into after exiting a portal.
Thor and Malekith slide down the outside of The Gherkin
And Mjolnir returns, breaking all the windows in the side of the building.
The Gherkin, also known by it’s given name, 30 St Mary Axe, is located a short walk away from Aldgate Underground Station. For Harry Potter fans I recommend teaming it with a visit to the close by Leadenhall Market.
