Secret Old London Guided Walking Tour
London’s best stories are often tucked behind office blocks and busy roads. This 90-minute walking tour leads you through the City’s older corners, from the place linked with William Wallace’s grisly end to a medieval churchyard, a moving memorial, and the remains of a Roman amphitheatre.
I like two things here. First, the route gets you away from the standard postcard circuit without sending you far from central London. Second, the guides, including Jess, Paul, Rosie, Jeremy, Pepe, and Matt, are praised for making the past lively with jokes, facts, and strong storytelling. The main drawback is simple: you are outdoors, so cold or wet weather can take the edge off the experience.

Key points to know before you book

- Roman, medieval, and wartime London in one short walk: The route covers several periods without asking you to spend half a day in a museum.
- Five compact stops with plenty of stories: William Wallace’s memorial, St Bartholomew the Great, Postman’s Park, Guildhall, and Smithfield Market each offer a different glimpse of the city.
- A small group capped at 20 people: This should make it easier to hear the guide and ask questions than on a large coach tour.
- Guides carry the experience: Jess, Paul, Rosie, Jeremy, Pepe, and Matt are all noted for humor, storytelling, and a clear love of London.
- A gentle walk with a central finish: You end at Guildhall Yard, about five minutes from St Paul’s Cathedral.
- Good value at $27.78: You are paying for a professional guide and a focused introduction to overlooked London, not entrance tickets or a full-day sightseeing program.
Why this corner of London is worth your time
The City of London can feel like a forest of glass towers during the working day. Look closer, though, and the pavement gives way to churchyards, old market traditions, memorials, and traces of the Roman city.
That contrast is the real subject of this walk. You are not simply ticking off famous buildings. You are learning to notice small clues: an old wall line, a quiet churchyard, an unusual plaque, or a street that still reflects an earlier use.
I especially like the scale. At about an hour and a half, the tour fits neatly into a morning or afternoon. It also leaves you plenty of time for St Paul’s Cathedral, the Museum of London area, or a longer walk along the Thames afterward.
The route appears designed for people who enjoy stories more than formal sightseeing. You will stop often, listen to the guide, and move on. Several stops have a bench available, which helps, but this is still an outdoor walking activity. Wear comfortable shoes and bring a coat, even if the forecast looks harmless.

Meeting the tour near Aldersgate Street

The starting point is on Aldersgate Street, by Underground Ltd in the Barbican area, with the tour finishing at Guildhall Yard. The end point is useful. You are about five minutes from St Paul’s Cathedral, so the walk can easily lead into another central London visit.
The group size is limited to 20 people. That is not a private tour, but it is small enough for the guide’s voice and expressions to carry without the impersonal feel of a large crowd.
One practical detail matters here: arrive early and identify the guide clearly. The supplied meeting instructions refer to a distinctive flag, and one unhappy booking involved confusion over the starting point and a departure only a few minutes after the scheduled time. The safest approach is to be in the correct place before the start time, look actively for the group, and contact the operator promptly if you cannot find it.
The tour is offered in English and uses a mobile ticket. Confirmation is sent when you book. Children must be with an adult, and service animals are allowed. Most people can take part, but you should be comfortable walking and standing outdoors for the duration.
William Wallace Memorial: a dramatic opening

The first stop is the William Wallace Memorial, where the tour points out the place associated with the Scottish resistance leader’s execution. It is a strong opening because it immediately pushes you beyond the usual royal palaces and famous bridges.
The stop lasts about five minutes and has no admission charge. Do not expect a large attraction with a long visit. The value is in the setting and the story, especially if your picture of Wallace comes mainly from film.
A guide can give this sort of place its proper weight. Without context, a memorial on a city street may take only a second to notice. With the story attached, you begin to see London as a place where power, punishment, and public spectacle shaped everyday streets.
St Bartholomew the Great: churchyard atmosphere

Next comes the churchyard of St Bartholomew the Great, one of the more impressive medieval sites on the route. You spend about five minutes here, walking through the churchyard and taking in the old setting.
The church has also appeared in the film Four Weddings and a Funeral. That film connection may appeal to movie fans, but the stronger reason to stop is the sense of age. The churchyard offers a quiet pause after the opening story and shows how much older London survives beside modern roads and buildings.
The tour does not list an admission ticket for this stop, so you should think of it as an exterior and churchyard visit rather than a guaranteed interior tour. If you want to explore the church fully, check separately whether it is open and whether an entrance fee applies at your chosen time.
This is one of the places where the walking format earns its keep. You can cross from the street into a more peaceful space in minutes, and the guide can point out details you might otherwise pass without a glance.

Postman’s Park and its moving memorial

Postman’s Park is the emotional center of the walk. You spend about ten minutes here, longer than at the other listed stops, and for good reason.
The park contains one of London’s most touching memorials, dedicated to ordinary people who died while saving others. The place is modest, but its subject is powerful. It asks you to think about courage in daily life rather than grand military victories or royal ceremonies.
This stop also gives the tour some breathing room. The stories are personal and direct, making a useful change from discussions of executions, Roman remains, or major institutions. You may find this the most memorable part of the walk if you prefer human stories to dates and architectural detail.
A quiet memorial like this works best with a guide who knows how to tell the story without rushing. The reported strengths of Jess, Paul, Rosie, and the other guides matter here. Their humor helps keep the overall walk light, but the best guides also know when a place needs a calmer tone.
Guildhall and London’s Roman footprint

The route then reaches Guildhall, described as a particularly handsome and easily missed part of the City. You also look for the site of London’s long-lost Roman amphitheatre.
This is a useful lesson in the layers beneath modern London. The Roman city is not presented here as a single preserved ruin you can wander through. Instead, the guide helps you locate its footprint and understand how an ancient arena once fitted into the urban plan.
The stop lasts about five minutes, so expect an explanation and a chance to orient yourself rather than a long archaeological visit. If you want an extensive Roman collection, you will need a separate museum visit. What this walk provides is a clear connection between the street in front of you and the city that existed below and around it centuries ago.
Guildhall also makes a good finishing area. From here, you can continue to St Paul’s Cathedral, only about five minutes away, or use the City’s transport links to reach another part of London. Ending in a central location adds real value to a short tour because you do not lose time returning to a distant starting point.
Smithfield Market after 800 years of trade

Smithfield Market brings the walk into a different kind of old London. The market has been used in London for more than 800 years, and passing through it connects the city’s past with a working tradition rather than a monument.
You spend roughly five minutes here. That is enough to hear why the market matters and to sense its place in the City, though not enough for a full market exploration.
This stop is useful because it widens the tour’s scope. London’s past is not only churches, memorials, and Roman ruins. It is also commerce, food, labor, and the practical business of feeding a city.
Market areas can be noisy and active, depending on the time and day. Keep close to the guide and expect the atmosphere to change from quiet churchyard to a more functional urban setting. The route is meant to show you how old uses persist, not to offer a dedicated food tour.
The guides make or break the experience

The strongest praise consistently centers on the guides’ delivery. Jess is described as an engaging narrator who can bring lesser-known places and old tales to life. Paul is repeatedly singled out for being funny, friendly, and well informed. Rosie is praised for warmth and storytelling, while Jeremy, Pepe, and Matt are also noted for making the walk easy to follow and enjoyable.
That variety matters because this tour is built around explanation. The stops themselves are free and mostly brief. You are paying $27.78 mainly for the person connecting them.
A good guide can turn a plaque into a story, explain why a quiet lane matters, and keep a mixed-age group interested. One particularly useful sign is the feedback from a family with two teenage sons, who found the tour their favorite part of a London visit. That suggests the guides do more than recite dates.
The tone seems relaxed rather than academic. You can expect facts, amusing details, and stories from Roman, medieval, and Second World War London. If you want a formal lecture with exhaustive architectural detail, this may not be your best match. If you like history delivered in clear, lively chunks, it should suit you well.
What $27.78 buys you
At $27.78 per person, this is a reasonable price for a short, guide-led introduction to central London. The five stops do not charge admission, so the cost is not covering tickets. It pays for the route, research, organization, and live storytelling.
That distinction helps you judge the value. If you only want to walk around the City with a map, you can see many streets for free. But you may miss the Wallace connection, the meaning of Postman’s Park, and the location of the Roman amphitheatre.
You also avoid the cost and time of a full-day tour. The compact route is useful on a first visit when you want a quick orientation, and on a return visit when the major sights no longer feel new.
The value is strongest for three types of people:
- You are visiting London for the first time and want context beyond the main landmarks.
- You already know central London but want stories in places you normally pass by.
- You enjoy a short, conversational walk and do not want a large group or a long commitment.
The value is weaker if you dislike outdoor tours, need a fully indoor activity, or want substantial time inside each church, market, or archaeological site.
Weather, pace, and comfort
Several positive accounts describe the walk as gentle and not tiring. The route includes many stops, and some locations have a bench available. Still, the activity lasts around 90 minutes, so you will spend most of that time outside.
London weather deserves practical attention. Cold wind and rain can make a fine route feel less appealing, and one account specifically found the walk uncomfortable on a cold day. Bring a waterproof layer and dress warmly in winter. In summer, a hat and water may help, though no special equipment is listed.
The guide’s pace also matters. Because there are five named stops and many short explanations, you should expect a steady walk with frequent pauses rather than long stretches of marching. Exact distances are not provided, so anyone with mobility concerns should ask the operator before booking.
The tour is near public transportation, which makes it easy to reach and easy to follow with another central London activity. The mobile ticket is convenient, but keep your phone charged and have the meeting details ready.
Who should book this London walk
I would choose this tour if I had already seen the Tower of London, Westminster, or the major royal sights and wanted a different side of the city. It is also a smart choice early in a visit because it may sharpen your eye for old details during the rest of your stay.
Families can do well here, especially with older children and teenagers who respond to stories of executions, Romans, medieval London, and wartime events. Children must have an adult with them, and the group format means younger children need to stay engaged during the explanations.
It suits solo visitors, couples, and small groups who want a social but not oversized outing. The 20-person limit gives the guide room to keep the group together and answer questions.
You should think twice if heavy rain is forecast, if you want a full interior visit to St Bartholomew the Great, or if you need a highly detailed Roman archaeology tour. This is a lively introduction, not a replacement for a museum or a specialist study walk.
Should you book Secret Old London?
Book it if you want London’s smaller stories, a short route, and a guide who can make overlooked streets matter. The combination of William Wallace, a medieval churchyard, Postman’s Park, Guildhall, and Smithfield Market gives you a varied ninety minutes for a fair price.
I would treat the weather and meeting point as the two things to manage carefully. Arrive early, find the flag and group, and dress for the conditions. If you do that, this is a practical way to see a quieter, older side of the City before continuing on to St Paul’s Cathedral or another central sight.
