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 used to eat lunch at Bastion 14, although you can't get anywhere near it now. There was plenty of old wall at Moorgate that was very open access.

From the article:

  London's original wall was 2 miles long, 6 metres high and almost 3 metres thick at its base

that states it ran from the Tower of London to the Museum in the Barbican.

> Note this is about the City of London

Not really. It’s about the Roman wall. It happens to be both in Greater London and around the City.

> Title should probably read "the City of London" rather than "London".

There’s only one Roman city wall in London, it is not ambiguous.

I had a hard time remembering that distinction when I first read about the "City of London".

Here is the US, the "city of Chicago" is the same as "Chicago".

> That car park in image [4] is wild. The juxtaposition of a mundane parking

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.

There's a Templar fortress in Lebanon that was occupied by militants a few years ago. 800 years old and still being used for its intended purpose.

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 :)

> 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.

As mentioned else comment, things were torn down and that served as the foundation for the next building.

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.

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.

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.

Shoes. All the way down. ;-)
