Head up at sunset for even more sensational sights.

It's easy to forget how beautiful the capital is when you're on the ground. Luckily, Horizon 22 is providing panoramic sightseeing of London from the city's second tallest building - and it's absolutely free.

It takes just 41 seconds for the speedy lift to whisk you up to the sky-high platform at 22 Bishopsgate. From there, stunning views are on offer of The Shard, Tower Bridge, St Paul's Cathedral and so much more. The riverside location also allows for an outlook over the Thames as far as the eye can see.

The 254 metre platform is Europe's tallest free public viewing gallery, meaning that even if you've been up in London's sky before, you're bound to get a different perspective from Horizon 22. So for a new outlook on the city, why not pay a visit to this high-up hotspot?

The platform can be found at 22 Bishopsgate viewing gallery, EC3V 4QT, and is open seven days a week. Looking for more rooftop outings? Check out the best London bars with a view, and find all the latest in our newsletter.
