Four Strange Places to See London's Roman Wall

  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.

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.

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.

Walking around Chicago I often see houses where the front door is a couple of meters below street level because the house never moved its door to an upper story when the city was releveled.

> 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.

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

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.

Edit: or Asia and Russia and South America...

In 1491 the point is made that the Inca believed that they had been beaten by superior gods and so they bowed out. But he doesn’t really talk about what happened to the Aztecs. You steal stone from structures you don’t care about anymore.

Didn’t Mexico see more intensive colonization? Settlers would care less about existing structures. Maybe the Spaniards built missions out of the wall.
