You’re likely here because you’re tired of the main Euston terminal. Honestly, the walk through the main Euston station concourse is a nightmare during peak hours, and if you’ve ever tried to find the Tube from the train platforms, you know the struggle of navigating that weirdly shaped basement. But Euston Square Underground station is different. It’s tucked away on the corner of Euston Road and Gower Street, looking like a tiny entrance to a secret bunker rather than a major transport hub. Most people walk right past it. They shouldn't.
It’s one of those spots in London that feels like a glitch in the Matrix. One minute you're dodging traffic on a six-lane highway, and the next, you're standing on a platform that feels remarkably unchanged since the Victorian era.
The Weird Geography of Euston Square Underground Station
Let’s clear something up immediately because it confuses everyone: Euston Square is not inside Euston station. They are separate buildings. If you are standing at the main line station where the Avanti West Coast trains arrive, you have to walk outside, cross the bus station, and trek about five minutes down the road to get to Euston Square. Why? Because the Metropolitan Railway—the world's first underground line—didn't want to play nice with the London and North Western Railway back in the 1860s.
They were rivals. Competition was fierce.
When the station opened in 1863, it was actually called Gower Street. It didn’t get its current name until 1909. If you look at the brickwork on the platforms today, you can still see the ghosts of that original design. It serves the Circle, Hammersmith & City, and Metropolitan lines. This makes it a tactical masterpiece for commuters. If the Northern Line is suspended at the main Euston station, you just walk here. Boom. You're on your way to Paddington or King’s Cross without breaking a sweat.

The station serves as a vital artery for University College London (UCL) and the Wellcome Trust. It’s essentially the "University Station" of London. You’ll see students clutching overpriced lattes and researchers looking stressed, all mixing with tourists who are definitely lost and trying to find the Harry Potter platform (which is actually at King's Cross, a ten-minute walk away).
Why the Architecture Actually Matters
The entrance is unassuming. It's a modest, single-story stone building that looks a bit like a glorified newsstand from the outside. But once you go down those stairs, the atmosphere shifts. Unlike the deep-level Tube lines (like the Northern or Piccadilly) which feel like being inside a giant vacuum-sealed pipe, Euston Square is a "cut-and-cover" station.
This means it was built by digging a giant trench in the road, laying the tracks, and then roofing it over.
Because of this, the ceilings are higher. The air feels... well, not exactly fresh, but certainly less like recycled carbon dioxide than the deep tunnels. There’s a specific smell to Euston Square—a mix of damp brick, old electricity, and the faint scent of rain drifting down from the entrances.

Survival Tips for the Platforms
Navigation here is simple, but there's a catch. The platforms are surprisingly narrow for the volume of people they handle. During rush hour, it gets tight.
- The Westbound Platform: This takes you toward Baker Street and Hammersmith. If you're heading to Marylebone, this is your best bet.
- The Eastbound Platform: This goes to King’s Cross St. Pancras, Farringdon, and eventually the City.
- The "Euston Tap" Factor: Directly above the station sits the Euston Tap, housed in one of the original 1830s stone lodges. It’s one of the best places in London for craft beer. If your train is delayed, don't sit on the platform. Go there.
The Connection Myth
Google Maps often tells you there is an "interchange" between Euston and Euston Square. Be careful with that. While they are "linked" for ticketing purposes (you won't get charged twice if you switch between them within a certain timeframe using Oyster or Contactless), there is no tunnel connecting them. You have to go outside.
If it's raining, you're going to get wet.
There have been talks for decades about building a direct underground walkway to connect the two. With the ongoing (and seemingly eternal) HS2 construction at Euston, those plans are technically on the table, but don't hold your breath. For now, the "Euston Square dash" is a rite of passage for Londoners. You learn to time the traffic lights on Melton Street like a pro.

Fact-Checking the Station’s History
A lot of "fun facts" about the Tube are actually nonsense, but Euston Square has some genuine quirks. It was one of the first stations to use moving stairs, though not in the way we think of modern escalators. It’s also famously located right next to the site of the old Euston Arch, which was tragically demolished in the 1960s—a move so hated it basically started the modern architectural conservation movement in the UK.
The station itself survived the Blitz, though the surrounding area was hammered. You can still see some of the original Victorian tiling if you look closely at the ends of the platforms where the modern advertisements haven't been slapped on. It’s a bit grimy, sure, but it’s authentic.
What to Do Nearby (Without Getting Lost)
If you find yourself with an hour to kill at Euston Square, don't just stare at your phone.
- The Wellcome Collection: Literally a two-minute walk away. It’s a free museum and library exploring the connections between medicine, life, and art. It has a fantastic cafe and some of the weirdest exhibits in the city.
- Drummond Street: Just north of the station. This is the holy grail of South Asian vegetarian food in London. Diwana Bhel Poori House is a legend for a reason.
- University College Hospital: It’s the massive building right over the station. If you see a lot of people in scrubs, that’s why.
Practical Logistics for 2026
The station is in Travelcard Zone 1. It is not fully step-free, which is a major drawback. If you have a heavy suitcase or a stroller, Euston Square is a bit of a nightmare. You’re better off heading to King’s Cross or using the limited lift access at the main Euston terminal if you can't handle stairs.
Wait times are usually minimal. Because three different lines run through these tracks, you rarely wait more than three minutes for a train heading into central London. The Metropolitan line is the "express" of the group—its trains are larger, have air conditioning (a godsend in July), and have transverse seating that makes you feel like you're on a "real" train rather than a Tube carriage.
Actionable Insights for Your Next Visit
- Avoid the Main Euston Tube Entrance: If you are heading to the City (Moorgate/Liverpool Street) from the Euston area, always walk the extra five minutes to Euston Square. You avoid the crushing depth of the Northern line and get a much more spacious train.
- Check the "Circle Line" Lies: The Circle line is notorious for delays. If the board says a Circle line train is 10 minutes away, check the Hammersmith & City line. They cover the exact same track through this section, so just hop on whichever comes first.
- Use the Gower Street Exit: If you’re heading to the British Museum, exit via Gower Street. It saves you a massive loop around the block.
- Hidden Toilets: There aren't any inside the station. Use the ones in the Wellcome Collection nearby; they are much cleaner and free.
Euston Square Underground station isn't trying to be flashy. It’s a utilitarian, slightly gritty, Victorian workhorse that serves as the perfect escape valve for the chaos of the main Euston terminus. Master this station, and you master north-central London travel.
