Sky Garden, London

Designed by Uruguayan architect Rafael Viñoly, 20 Fenchurch Street is better known by its catchier nickname—the “Walkie-Talkie.” Why? Well, because it looks exactly like one, just supersized and stuck smack in the London skyline. Not everyone is a fan of its chunky silhouette, but love it or mock it, the building makes quite the statement—and unlike most skyscrapers, it actually lets the public in for free.

At the top sits the Sky Garden, a three-story glass crown perched on the 35th, 36th, and 37th floors. To get in, you’ll need to be quick on the click—free tickets drop every Monday, and they vanish faster than a London cab on a rainy night. Once you’ve secured your spot, you’ll be treated to one of the best panoramic views in the city, complete with a side of wine or dinner if you book a table. Yes, the bars and restaurants stay open late for those who like their skyline with a cocktail.

From this lofty perch, the view is a who’s who of London’s architectural elite: look south for the jagged elegance of The Shard, or north for a full lineup of nicknamed giants—Tower 42, the Gherkin, the Cheesegrater, the Scalpel, and the tall-and-polished 22 Bishopsgate.

As for the “garden” part of Sky Garden, it’s not just a name. You’ll find a leafy collection of semitropical trees, succulents, and flowering showstoppers like African lilies, Red Hot Pokers, and Birds of Paradise, all bordered by wafts of French lavender. It’s basically a high-rise greenhouse with views, drinks, and a better Instagram ratio than most city parks.

Bottom line: whether you’re a lover of lush greenery, skyline spotting, or just in it for the gram—the Walkie-Talkie talks back.
