The Sky Garden is a public space at the top of the Walkie Talkie building, (officially known as 20 Fenchurch Street) which opened in January 2015. It is home to restaurants and bars, plenty of foliage and great views of London. It is the highest garden in London and despite being only half as tall as the Shard, it’s well worth a visit (and it’s free!)
