As far as capital cities go, London is big. It's the largest capital in Europe and has land mass of over 1500 square kilometres. Within that space, over 8.5 million people from all over the world live, work and play, and a further seventeen million people visit the city each year.
Those are big numbers for an undeniably enormous city. But you only get a sense of London's vastness when you're above it, so naturally, we took to the skies in a London Helicopter for a full 18 minutes of gawping at one of the world's greatest cities.
If you're flying over London or on the flight path into Heathrow, these are the astonishing views you should look out for:
St Paul's Cathedral
Lottie flew with The London Helicopter, which has 18-minute London Sights flights starting from £200 per person. Explore London with the Rough Guide to London.
