If you’re in London and love great buildings, you’ve got a lot to see. The city mixes centuries‑old cathedrals with sleek skyscrapers, and the best way to enjoy it is to plan a simple route that covers both the old and the new. Below you’ll find the top spots, how to avoid the crowds, and quick hacks for great photos.
Start your day at St Paul’s Cathedral. The dome dominates the skyline and hosts royal events, so you’ll often see a crowd of tourists. Arrive early (opening at 8:30 am) to beat the rush. Grab a free audio guide at the entrance – it explains the dome’s engineering in plain English and points out the hidden altar behind the nave.
Walk east across the Thames to the Tower of London. The White Tower is a perfect example of medieval stonework. The Crown Jewels draw the biggest queues, but the surrounding walls and the famous ravens are free to explore. Wear comfy shoes; the cobbles get slippery when it rains.
Next, head to Westminster. Big Ben’s clock face is a Gothic‑Rev masterpiece. You can see the clock up close from the Westminster Bridge walkway – no ticket needed. If you want to step inside the Elizabeth Tower, book a slot online at least two weeks ahead; the tour lasts about 45 minutes and includes a climb up the spiral stairs.
Don’t miss the British Museum’s Great Court. The glass roof, designed by Foster + Partners, blends modern design with classic stone arches. It’s free, and the sky‑lit ceiling makes for an easy Instagram shot without any crowds.
After the historic tour, jump to the South Bank for the Shard. At 310 m, it’s the tallest building in the UK. The viewing platform on level 72 offers 360° views. Book the “Early Bird” ticket for 9:30 am – you’ll get a discount and fewer people. Bring a light jacket; the glass can get chilly.
Just a short walk away, the Gherkin (30 St Mary Axe) stands out with its curved glass façade. You can’t go inside without a corporate booking, but the exterior is impressive from the public promenade on the River Thames. For a closer look, join a free guided walk that starts at the nearby Liverpool Street station on Saturdays.
If modern art interests you, swing by the Tate Modern’s switch‑tower entrance. The building was a former power station, and its massive turbine hall now houses large‑scale installations. Admission to the main galleries is free, and the river viewpoint on the roof gives a perfect skyline backdrop.
Finish your architectural day with a night stroll along the River City. The illuminated London Eye and the sleek design of the O2 Arena create a futuristic silhouette. Grab a quick bite at a riverside kiosk – many offer a “view‑only” menu that lets you enjoy the lights without the hassle of a full sit‑down meal.
Quick hacks: download the Citymapper app for real‑time transit updates, use a contact‑less payment card for the Tube, and carry a small tripod for steady shots in low light. With these tips, you’ll see the best of London’s famous architecture without feeling rushed.
