Note, those pictures depict the towers as about 5x bigger than they actually were.
To get a true sense of scale, here's the same view on Google Earth: https://earth.google.com/web/@44.48152905,11.33820409,94.60421062a,3857.75677249d,35y,-159.75723051h,84.72408363t,0r https://earth.google.com/web/@44.48152905,11.33820409,94.604... You can see the towers that are still standing. They visibly stick out from the shorter buildings, but they're nowhere near as big as in the picture.
- 2-3-7-43-1807 2y agoI think Google Earth might be more wrong than the illustration. One of the two Towers of Bologna is 97m. On GE it looks less than that. 97m is more than 33 stories. https://en.wikipedia.org/wiki/Towers_of_Bologna https://en.wikipedia.org/wiki/Towers_of_Bologna
- sidewndr46 2y agoWhy do people attempt to use "stories" as a measurement of height? There is no universal agreement for what a "story" is. 97 meters is in fact 97 meters.
- TulliusCicero 2y agoBecause it's evocative, it's easier to imagine what it looks like.
- LtWorf 2y agoExcept that at some point one story was twice as tall as they are now.
- kdazzle 2y agoI think the universal agreement is actually to measure things in football fields
- llm_trw 2y agoNow if we could only agree if we should use soccer or handegg field sizes.
- vundercind 2y agoHandegg, because there’s an actual standard size for them. Which is a worse decision for a sport but makes them better for measurement. Soccer’s trying to make their sport worse by standardizing, but they’re not there yet.
- bmacho 2y agoIt will be more appealing to nerds when they could say "transition frequency of the caesium 133 atom"
- throwup238 2y agoThe number of atomic transitions a cesium 133 atom makes when fired across a football field at the speed of sound.
- tuatoru 2y ago... in dry air at STP.
- rascul 2y agoWhich handegg field size though? There is not just one standard. I think we should use the Canadian size, since they created it.
- whiterock 2y agowhich is also not normalized. A referee once told me that - in theory - football fields can be square. I think it was 80m x 80m since 80m is the minimum length and the maximum width. Correct me if I am wrong.
- Mountain_Skies 2y agoGoing to play the pedantic card and mention that there's also no universal agreement on how to measure a building's height. The Council on Tall Buildings and Urban Habitat on its own has three different methods and not everyone accepts those as being the correct and true way of measuring the building's height.
- jltsiren 2y agoI think everything in the illustration is at least twice too high. The walled part of Bologna was ~1 km in diameter at that time, and the tallest towers were ~10% of that. The model in Google Earth looks about right, at least if you compare it to this: https://static.bolognawelcome.com/immagini/ac/57/95/5d/20220601101753_landscape_16_9_desktop.jpg https://static.bolognawelcome.com/immagini/ac/57/95/5d/20220...
- LtWorf 2y agoThe illustration is modern, by an artist.
- timmaxw 2y agoReally? I zoomed in on the Towers of Bologna and then used the "measurement" tool to draw a 97m line on the ground. The line seems about as long as the tower is high. If you try that, do you get the same result?
- asimpletune 2y agoI live in Bologna. The few towers that remain are all very tall, but the largest one is extremely tall. It makes more sense if you see them from an opposing hill, but they literally tower. https://share.icloud.com/photos/042jP_mGA1W1thRhqv3ez4p3w https://share.icloud.com/photos/042jP_mGA1W1thRhqv3ez4p3w
