Dotted around London can be found various remnants of the original Roman Wall that once encircled it, yet one fragment is rarely seen, despite being in full view of those who know where to find it.

Should you walk along the appropriately named London Wall road, you might notice a row of concrete blocks acting as a temporary wall, and it is just underneath them that can be found one of the larger intact remains of the Roman Wall.



But how to see it?

In fact, it’s exceptionally easy, if you know how.

For that vast road that cuts through the City, once part of a planned, and fortunately abandoned ring road network sits on top of another road that runs underneath it. That is, in fact, a subterranean car park and during its construction, the Roman Wall was uncovered.

This fragment of Roman Wall is all that remains of a longer section of walling (of about 64m) which was uncovered in 1957 during clearance works for the new road and was, for the most part, subsequently demolished during the construction of the road and car park.

As much of the Roman Wall was actually later Medieval conversion, that demolition is not as heinous a crime as it might sound.

Still, a bit of a shame though.


Anyway, to see this fairly fine remaining section, head over to the Museum of London, and then locate a suitable entrance into the underground car park. My preferred route is the staircase down from next to the above-ground section of London Wall next to the museum that leads directly to the car park.

Here, it’s a long walk along an empty (at weekends at least) car park that echoes to the sound of clomping feet as you stride along the long underground road to the very far end. And here, nestled amongst the motorbikes and motorcars, a wall built in the era of the horse-drawn chariot.


It’s not the nicest location, and the smell of car parks always makes me feel light-headed in a bad way. Yet, being hidden from casual discovery and not put into a sanitized display case makes it all the more appealing to visit.

Sadly, the fragment, and the nearby gatehouse are considered to be at risk by English Heritage due to the poor surroundings.

Do note that as it is in a car park, you probably want to let the security staff in the office halfway along the car park know you are heading down to look at the Roman Wall. They seemed quite happy with my visit.


Still buried, further sections of London Wall lie concealed approximately 58m to the east and 120m to the west of this section. Obviously, you can’t see them!

However, next month is a rare opening of the Roman Bath House locked underneath an office block, which is really worth a visit.

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

Thank you

    Fascinating. I had no idea this was accessible to the public.
    I hope, but don’t know, that the still buried parts might be protected by them still being buried. Shame the remodelled part got destroyed, it would have been interesting to see the difference.
    Thanks for the great photos.

    I think Underground Carparks are fantastic spaces in their own right, almost cathedral-like when large enough. Portsmouth has Europe’s largest (unless something bigger has been built in the past decade?) and it quickly becomes a great geometric form (particularly when empty).

    I am told that there is another part of the wall underneath the Old Bailey.

    I saw this today (thanks SO much to IanVisits).
    I tried but failed to get my bearings in order to establish precisely which bit of the Roman Fort/Wall it is. If the car park runs under London Wall (the modern road) then it it must be just south of the north-east corner of the fort, and not actually part of the subsequent main London Wall. But the angle doesn’t seem quite right.
    Can anyone enlighten me? Ian?
    Is anyone there……

    I was down there on 18 March after one of the Museum of London west fort gate remains tours (locked room, west end of the car park, see M of L site for future dates). In answer to TW’s question, the wall remains in the car park are the city wall, not the fort wall. The west end of the car park is adjacent to the west wall of the fort; at about 200m along the car park you will be crossing where the east fort wall would have been; the wall remains in the car park are about 300m from the entrance.
    On the surface, the west fort wall is shown by the visible remains of various ages adjacent to Noble St, and in the Gardens by the side of the M of L, the centre-line of the fort is very close to the alignment of Wood St, the east fort wall would have followed the line of the footpath Brewers’ Hall Gardens. The wall in the car park corresponds to a point not all that far from where Fore St Ave meets London Wall (the street). It is almost in line with, but at a very slight angle to, the north fort wall, remains of which are in St Alphage Gdns.
