The Globe Arena looks like a big golf ball but is actually the world’s largest spherical building. Not much of a surprise there, it had to be the world’s largest or tallest something

This is the Silverstone racing circuit home of yesterday’s British Grand Prix. The track is half in Northamptonshire, half in Buckinghamshire, and you can still see the classic configuration of runways from when this used to be a World War II airfield. During the Grand Prix the airfield becomes the busiest in the UK, complete with its own air traffic control, and supposedly with a helicopter taking off every 8 seconds! (Wikipedia page)

If you look closely you can actually see cars driving round (there’s one visible in our thumbnail), and at the intersection of two runways in the centre of the track you can clearly see 3 bright red cars - a Ferrari presentation perhaps?

Thanks to Thomas, David Patrick, Rob, Mark, David Patrick, Paul Marciano, Steve Owen, Lianachan, Jan Koubek, Huw Morris, Rickard Jensen, Nick, Adam Sadler, Mario Sarno, Alessandro Guerra, Sean, Markus, Daniel Jibouleau, Kevin S and Stewa.

Update: After much debate in the comments of this post, determined reader Patrick has finally tracked down the truth about this mysterious location! Patrick contacted a friend who lives in Mexico and she pointed him towards this forum thread, where he discovered that this is a place called La Lobera; and our ‘hole in the coast’ is in fact, a collapsed sea cave. There’s some brilliant images of the hole and the surrounding area in the thread, some of which show the structure to be of pretty staggering size.

Many thanks and much kudos to Patrick, as this was driving us nuts!

Anyone know what this strange hole in the coast of Mexico is? Weird.
