they should have called it parliament, not cathedral. BBC don't know the meaning of the word cathedral, or was this intentional to trigger some kind of reaction from religious groups.

I've heard the term "Cathedral" used quite often to describe massive enclosed spaces, especially if the interior surface is stony or hard.

It's a favourite in the caving community to describe very large, well, cathedrals in cave systems.

I have been to this place. It is limited viewing, requires a reservation & the slots run out practically in seconds. Tough for us residents to get it as well. My wife could snag it in her third try, as a late birthday trip last year. It is gargantuan & having massive holding capacity. To give semblance with something familiar, it was like standing in NY Grand Central station, except it was felt bigger, empty, damp &…

> In addition to this underground chamber, there are two massive pumps on either sides, which divert the water from whichever river is surging to the other (Arakawa & Edogawa possibly). You probably mean pumping stations right? Usually single pumps don’t have that kind of flow rate. Just a nit pick though, your comment was really interesting!

I'm sorry, yes, two stations with huge pumps. They are like towers, but built from basement level downwards if that impression makes sense.

In a similar vein is the surge shaft being built as part of the Snowy 2.0 scheme in Australia. 28 metres diameter and 263 metres deep. It absorbs the momentum of the surge of water when the downstream power station closes its valves. https://www.snowyhydro.com.au/wp-content/uploads/2024/01/SH_...

Not the same power station, but I have to post a link to one of my favorite YouTube videos: https://www.youtube.com/watch?v=fJVBlhgt9j8 (Obere Wasserschlosskammer).

Weird, I visited last year and don't remember having a hard time getting tickets. Maybe I got lucky. Here are a couple photos I took with people for scale: https://imgur.com/a/DPYYou4

Thank you for these; they convey the relative proportion very well and have satiated my curiosity.

> “It’s like a science-fiction kind of facility,” says JICA’s Inaoka, whose job involves collaborating with experts from developing countries to share Japan’s expertise.

My first thought upon seeing the photos was that this was the inspiration for many of the indoor levels in the original Half-Life. All that's missing are the headcrabs.

The one with the stairs could've been ripped straight from the original Half-Life. Makes me want to play it again. Thank you for the reminder.
