Not London Wall related but the London Bloomberg HQ when it was built reconstructed the Temple of Mithras at the actual position, quite deep underground.
The Museum of London site (now closed as they prepare to move to their new site, coincidentally near the AWS HQ), and there was a window you could look down on part of the wall, which you can also see from the other side of the road near Barbican. I won't give directions, as that seems futile anywhere near Barbican, but I had only just thought about how weird it is that there is wall at Tower Hill, and wall at Barbican - they can't be the same run of wall as it was built, can they? That'd be immense...
The new Museum's site also has a very cool view through a window, but it's a view of the passing trains [underground], because historically that building (one of London's markets) had a freight service and of course there's no room to move a railway line under London so even though it hadn't needed a freight service for decades the passenger service over the same rails still exists and you will be able to wave to surprised (if they haven't taken that route before) passengers from inside the museum.
A friend lucked into (there's literally a lottery for popular sites) tickets for the new site in Open House London 2024 and the window existed but wasn't really set up for tourists yet of course.
I'm terrible at keeping secrets so, it was probably a bad idea to let me go on the tour, or, perhaps we should try to have fewer secrets so that I'd remember ?
There is a London Wall Walk, starting at the Tower of London. Text copied from the plaques at the postern: (thanks Google Lens)
>The London Wall Walk follows the original line of the City Wall for much of its length, from the royal fortress of the Tower of London to the Museum of London, situated in the modern high-rise development of the Barbican. Between these two landmarks the Wall Walk passes surviving pieces of the Wall visible to the public and the sites of the gates now buried deep beneath the City streets. It also passes close to eight of the surviving forty-one City churches.
The Walk is 134 miles (2.8km) long and is marked by twenty-one panels which can be followed in either direction. Completion of the Walk will take between one and two hours. Wheelchairs can reach most individual sites although access is difficult at some points.
If you're in the vicinity of the road called London Wall (where the car park referenced in the article is) then it's only a short walk to London's Roman amphitheatre [1]. It doesn't seem to be very well known but is quite impressive. It's one of very many bits of Roman history entombed in basements of London buildings.
The Merrill Lynch Financial Centre also has a big chunk of Roman stuff in the basement - but there's no public access and no access to the walkway around the ruins even if you're an employee.
Very few people on HN will have been alive when there was a county of London. It ceased to exist in the 1960s.
The UK does not require this layer of subdivision to exist, so it's not that there's a different county or set of counties covering the same area now but rather there is no county. This is a contrast to say the US system where AIUI there must be a county and in some cases that county doesn't really matter (e.g. New York County in New York City aka Manhattan) but it has to exist anyway.
City status is very different here, the Monarch (ie now Charlie) gets to decide what is or is not a city, but because that's arbitrary it also has very few consequences, it's a cosmetic basically, you can write "City" on some signs if you like, but if you feel like a small town you still feel like a small town, and if you already feel like a bustling city then having the word doesn't make a real difference.
For even further confusion "London" actually contains two cities: London and Westminster. London was a walled city but Westminster was not. So "London" was we know it today is more like Westminster than London.
A cathedral is neither necessary nor sufficient for city status. City status in the UK is given by the monarch and that's all there is to it. Cambridge is a city without a cathedral and Bury St Edmunds is a town with a cathedral.
New York is an obvious example of two entities of the same name, with the “City of” version being a small part of the larger version. It’s just on a much bigger scale.
I worked for Lloyd’s Register for a spell, and their cafeteria was where the Vine Street building is, just got used to eating lunch there by the bits of wall everyday for a few years.
For more of this sort of thing, check out the Old Structures Engineering blog. Don does a post a day, day in, day out -- so obviously some are more detailed than others. I enjoy having it in my feed.
For another interesting mix of new and ancient, check out the Serdica metro station in Sofia, Bulgaria. [0] It's fully inside an excavated Roman-era ruin. Very cool!
That car park in image [4] is wild. The juxtaposition of a mundane parking garage built directly on top of ancient Roman ruins is incredible.
It's a powerful reminder of the layers of history we're living on top of. Thanks for sharing.

Meh.
Let me introduce you to Colchester, the oldest recorded town in the UK. The wall behind the carpark you see here is the original Roman wall (circa 65 AD) with modern brick on top... (The tourist sign is in the foreground if you zoom in). The walls were built after the city was sacked by the rebel queen Boudica in 60 AD.
Oh, and if you rotate the streetview 180 degrees, between the trees you can make out the ruins of St Botolph's Priory, sacked during the dissolution of the monasteries in 1536 AD. It's a nice place for a lunchtime picnic.
Not bad engineering to make it through a handful of civil wars, a Blitz, and a couple thousand V-1 rockets mostly intact. You have to wonder how long all the steel and concrete that's been laid around the Thames from our civilization will last.
Most of the wall has been plundered for stone and to make way for new development over the past millennium. Its not conflict that has destroyed 2 miles of a 6m high 3m thick wall, it's peace :)
If you leave ground alone all sort of things grow on it or lay on it. Dirt, mud, leaves etc. Soil grows at about 1 mm per year. 1 meter in 1000 years.
Historically cities were hit by floods and wars and new buildings were built on top of the foundations of old ones. We had an article about that church in Rome built over another roman church built over another roman church, etc. down to an old temple on a spring, or something like that.
It might even happen faster than that. If I don't sweep my cement patio for about a month, the decaying leaves from the bushes are enough to make about an 1/8th inch of fresh brown soil under the leaf piles.
> Delgado received his first big assignment back in 1978 while working for the National Park Service: excavating and studying the remains of the Niantic, one of the first whaling vessels that brought gold-seekers to the area. It had been discovered near the Transamerica Pyramid at the corner of Clay and Sansome streets. After being left behind during the Gold Rush, the ship had been repurposed to serve as a storeship, saloon, and hotel until its demise in an 1851 fire.
Before industrial demolition was common, old buildings would be town down and material repurposed for new constructions, build on top of existing foundations and rubble. Do this enough over the centuries and your city will slowly rise in height.
If anyone’s ever in Barcelona I recommend checking out the history museum, which is literally built on top of some Roman and medieval ruins. You can descend into the basement to see the excavated remains of the foundations of Roman buildings that had been levelled and built on top of.
Every time a building fell apart due to earthquake, fire, flood, war, abandonment- the good material was taken for reuse and the bad material became rubble which was often smoothed out and used as a foundation.
