Sky Garden, London

Designed by the Uruguayan architect Rafael Viñoly, 20 Fenchurch Street is commonly referred to as the "Walkie-Talkie" due to its distinctive resemblance to a radio handset. Although not without its share of controversy, primarily because of its shape and prominent position in the city skyline, it stands out as one of the few skyscrapers offering free public access. To gain entry to the Sky Garden, a three-level observation deck, visitors need to make advance reservations. Tickets are made available every Monday for bookings up to three weeks in advance and tend to sell out rapidly. The bars and restaurants within the Sky Garden remain open until late.

This location serves as an ideal vantage point for taking in the views of London's other towering structures. To the south, you can spot the Shard, while to the north, you'll find Tower 42, the "Gherkin", the Leadenhall Building (also known as the "Cheesegrater"), "The Scalpel", and 22 Bishopsgate, the tallest skyscraper in the City.

The garden itself features semitropical trees and succulent plants that create a natural border around the bars, restaurants, and expansive walkways spanning the 35th, 36th, and 37th floors. Among the flowering plants, you can admire African Lilies, Red Hot Pokers, and Birds of Paradise, accompanied by aromatic herbs, particularly French Lavender.
