Join us as we explore these delightful discoveries that promise to enrich your visit and reveal a different side of London.
Ceremony Of The Keys
- Location: 35 Tower Hill, St. Katherine’s & Wapping | Time: 9:30 pm to 10:05 pm | Nearest Tube Station: Tower Hill
The Ceremony of the Keys is one of London’s oldest traditions. Located near London’s iconic bridge, it has been held every night at the Tower of London for over 700 years. This ancient ritual marks the locking of the Tower’s gates.
This practice not only symbolizes the security of the Crown Jewels but also reflects the fortress’ rich history. As the sun sets, the Chief Yeoman Warder of the Tower, performs this ceremony. Clad in a distinctive uniform, his nightly ritual draws visitors into a world of history and heritage.
The event is complimentary, and although the wait to get tickets is lengthy, do not pass up this opportunity to witness a century-old London tradition. It’s essential to note that photography is strictly prohibited during the ceremony, and the Yeoman Warders are vigilant in enforcing this rule.
Churchill War Rooms
- Location: Clive Steps, King Charles Street, Westminster | Nearest Tube Station: Westminster or St. James Park
On a day trip to London, I stumbled upon Churchill’s War Rooms. Unlike the city’s famous landmarks, this underground museum isn’t heavily advertised. But this hidden gem beneath the streets of Westminster,
completely captivated me.
As I walked through the preserved bunkers, I imagined what it was like during World War II, when Churchill and his team planned their wartime strategies here. Seeing his bedroom and the Cabinet Room was surreal. Stepping back in time, the atmosphere was intense and immersive.
If you’re interested in London’s bygone days, don’t miss this powerful slice of history. It’s unforgettable and profoundly moving.
Postman’s Park
- Location: King Edward St. | Nearest Tube Station: St. Paul’s
In a city full of parks, Postman’s Park stands out for its moving tribute to everyday heroes. Just north of St. Paul’s Cathedral, it features a memorial to people who died saving others. At first glance, it looks like any other garden. But a closer look reveals a wall lined with ceramic plaques honoring acts of bravery.
Created by the philanthropist George Frederic Watts, the memorial features Doulton glazed tiles that detail each selfless act. Some drowned, others died in fires or train accidents. The most recent plaque honors Leigh Pitt, who drowned in 2007 trying to save a child.
I was touched by the ones that featured William Fisher (aged 9) and John Clinton (aged 10). These were ordinary Londoners, many of them young. Though their lives were brief, their courage lives on in this quiet, beautiful park.
The Vaults
- Location: Leake Street, under the Waterloo Station | Open: Hours vary
If you’re drawn to the strange and surprising, make your way to The Vaults. Tucked beneath Waterloo Station in a network of old railway arches, this underground space is a haven for alternative art and performance. We found the entrances hard to find, but it’s worth the search.
Its graffiti-streaked tunnels lead to a theatre that thrives on the bold and unconventional. The rough, industrial setting adds to the intensity. Don’t expect glitz or gloss here. It’s unfiltered, unpredictable, and refreshingly offbeat.
Neal’s Yard
- Location: Covent Garden, Camden | Nearest Tube Station: Covent Garden
Located in Covent Garden, Neal’s Yard was one of those places we stumbled upon and never forgot. Originally developed by Thomas Neale in the 1600s, it now offers a bright, quirky escape from the rush of central London.
The small courtyard buzzes with life. Expect independent cafés, colorful storefronts, and an artsy, laid-back vibe. It’s the kind of spot that invites visitors to slow down, grab a coffee, and take it all in.
On one wall, there’s a playful mural of Princess Diana as Mary Poppin. It’s just one of many little surprises that make this hidden corner feel so special.
Temple Of Mithras
- Location: 12 Walbrook, Westminster | Nearest Tube Station: Cannon Street
The London Mithraeum, opened in 2017, brings the ancient Temple of Mithras back to its original site. Discovered in 1954 during construction, the temple dates to the early third century and once served followers of Mithraism, a Roman male-only cult.
Built underground to mimic a cave, the temple’s layout, with a central nave and altar, echoes that of a modern church. Today, visitors can explore its history, view Roman artifacts, and experience an atmospheric reconstruction with chanting and light effects.
Sky Garden
- Location: 1 Sky Garden Walkway | Nearest Tube Station: Monument
Being the highest public garden in London, Sky Garden offers spectacular views of the iconic skyline. Located at the top of a skyscraper at 20 Fenchurch Street (Walkie Talkie building), it’s complimentary to visit the lush, multi-story atrium.
While most view London from expensive attractions such as The Shard or the London Eye, Sky Garden is a little-known retreat. However, tickets are limited and must be reserved in advance online.
London’s Sky Garden has an outdoor observation area, which the covered atrium is welcoming during a rainy London day. The views are impressive during the day, but at sunset, the remarkable city comes alive in a myriad of twinkling lights.
Explore Little Venice
- Location: Off Blomfield Road | Nearest Tube Station: Warwick Avenue
Escape London’s busy streets and unwind in Little Venice, a peaceful pocket of canals and calm. Reminiscent of its Italian namesake, this scenic area is renowned for its charming pubs, cozy waterside cafés, and a relaxed atmosphere.
Primarily residential, it comes alive in the summer, offering a free, less touristy way to experience the city. We enjoy strolling along the canals, admiring the architecture, or hopping on a colorful narrowboat to Camden Locks.
For something playful, don’t miss the puppet theatre barge. This quirky floating stage that’s been entertaining all ages for over 30 years.
Kyoto Garden
- Location: Holland Park Ave, Kensington | Nearest Tube Station: Holland Park
Kyoto Garden, a peaceful retreat in Holland Park, is a hidden gem gifted by Japan in 1991 to honor UK–Japan relations. It’s a perfect escape from London’s crowds—tranquil, beautiful, and unforgettable.
This serene Japanese garden features stone pagodas, rock gardens, and maple trees. They surround a koi-filled pond that invites quiet reflection. The calm is occasionally stirred by peacocks wandering through the greenery.
Leadenhall Market
- Location: Gracechurch Street, Langbourn | Nearest Tube Station: Monument
Featured in Harry Potter and the Philosopher’s Stone, Leadenhall Market is a stunning covered arcade in London’s financial district. It’s known for its cobblestone walkways and colorful Victorian ceiling.
Though it no longer functions as a market, the space is now home to pubs, boutiques, and upscale restaurants. Dating back to the 14th century, its Neo-Gothic charm and intricate design make it a favorite for fans, photographers, and architecture lovers alike.
Smaller than it looks in photos, Leadenhall still stands out as one of London’s most striking hidden gems. Maybe not so hidden, thanks to the web.
St. Dunstan’s In The East
- Location: St Dunstan’s Hill, Billingsgate | Nearest Tube Station: Monument
Tucked between London Bridge and the Tower of London, St. Dunstan’s in the East is a peaceful garden built within the ruins of a bombed-out church. Left in ruins after World War II, it was transformed into a public garden in 1970.
Ivy climbs the stone walls, flowers drape the arches, and a central fountain offers a space to reflect. Now surrounded by modern buildings, it’s no longer a hidden gem. With growing crowds and cameras, early visits provide the best chance to enjoy its solitude.
The Thames Barrier
- Location: Eastmoor St, Royal Docks | Open: Visitor’s Centre hours vary by season
The Thames Barrier, which opened in 1982, protects London from flooding. Spanning 520m across the Thames, it’s a feat of engineering often missed by visitors since it’s outside central London.
I took a boat from Westminster to see it and marvel at its engineering. It’s also visible from the north bank (Thames Barrier Park, near Pontoon DLR) and the south bank (Thames Barrier Info Centre, with a small fee).
The barrier has 10 rotating steel gates that lie flat on the riverbed but rise to block floodwaters during storms. Built to protect London until 2030, it’s now expected to last until 2060-70.
London Silver Vaults
- Location: 53-64 Chancery Lane, Holborn | Nearest Tube Station: Chancery Lane
The London Silver Vaults hold the world’s largest collection of silver. Once a secure vault for silver, this steel-reinforced basement now houses over 30 shops selling silver products.
Though WWII destroyed the building above, the 1.2m-thick walls kept the vaults intact. Walking through the vault door feels like entering Fort Knox. Two floors are filled with glittering silver cutlery, teapots, jewelry, and figurines, some dating back to the 16th century.
Churchill Arms
- Location: 119 Kensington Church Street, Kensington | Nearest Train Station: Notting Hill Gate
At the Churchill Arms, pub goers can sip a pint surrounded by flowers. This London pub is adorned with 200 plants covering its exterior year-round, swapped for evergreens and lights in winter.
Named after Winston Churchill, whose grandparents once frequented this establishment, it boasts a classic British pub vibe. Its interior features dark wood, a central bar, and memorabilia from the Churchill era.
Crossness Pumping Station
- Location: The Old Works, Bazalgette Way, Bexley | Nearest Train Station: Abbey Wood
A Victorian sewage plant might not sound like a tourist spot, but Crossness Pumping Station is a stunning surprise. Built in the mid-1800s, its ornate ironwork and vibrant colors evoke a cathedral-like atmosphere.
Created after London’s “Great Stink” to move waste downriver, it was a significant feat of engineering.
Sewage separation came later, and by the late 1900s, the site was closed. Now restored, the so-called “Cistern Chapel” features bold period colors. At its heart is the Octagon, an intricately decorated space of maroon columns and green fig leaves. A hidden gem worth seeing.
Shoreditch
- Location: Borough of Hackney in London’s east end | Nearest Tube Station: Old Street
While most travelers rush to big-city landmarks, it’s often the hidden spots that stick with you. Take Shoreditch, for instance—a creative hotspot where street art covers almost every wall.
Murals, stencils, and paintings pop up everywhere, some even decorated with beads or pearls. If you want to get the full picture, a street art tour can show you pieces you’d likely miss on your own.
And if art’s not your thing, Shoreditch still delivers with Michelin-starred dining, quirky shops, street food, and trendy cafés. It’s a great reason to explore parts of London.
