Tips for Visiting

Plan your route using a map app that shows walking distances. Most of these sites are within a short walk of each other, so you can hop from one to the next without needing a car.

Buy tickets online whenever possible. It saves time and often gives you a discount. For places like The Shard or Sky Garden, booking a few days ahead guarantees a spot.

Check opening hours before you go. Some historic buildings close early on weekends, while modern towers stay open later.

Bring a compact umbrella. London weather changes fast, and you’ll thank yourself when you’re still dry while snapping photos.

Finally, take a moment to look up. Many of these buildings have interesting details you’ll miss if you’re only focused on your phone. A quick glance at the carvings, the glass patterns, or the stonework adds depth to the experience.

With this short guide, you can explore London’s architectural gems without feeling rushed. Grab a coffee, put on comfortable shoes, and enjoy the city’s best buildings – they’re waiting right around the corner.
