I think that it would be worthwhile to mention that during the years 1880 to 1890 there were four interesting buildings (or structures or something) finished. The first was Cologne Cathedral, which finished in 1880. The building of it started in 1248, but it didn’t finish to 1880 and at that point it became the tallest building in the world. Ulm Minister, which was started in 1377, was finished in 1890 and became (and remains) the tallest church ever built. It would have become the tallest building ever built, but there were two buildings finished between 1880 and 1890 that were completely different from anything previously built.
One was the Eiffel Tower, finished in 1889. The other was the Washington Monument, which passed Cologne Cathedral in 1884. I think that the Washington Monument is the weirdest building ever built. Remember that this decade was just before the age of skyscrapers. The Eiffel Tower is weird enough in itself, since it’s essentially the steel understructure of a skyscraper with nothing covering it. The Washington Monument is the tallest building ever built without a steel understructure inside it. (There’s a steel understructure that supports the elevator in it but not the Monument itself.) And nobody is ever going to be crazy enough to ever build another like it that’s taller. The whole idea of it is weird. It’s build on the model of an Egyptian obelisk, but it’s ten times as large as any Egyptian obelisk. It is in the middle of a city with no tall skyscrapers at all, so it really sticks out.
I suspect that someone is going to quibble about what is a building or a structure or whatever. Look, none of these building have people living in them. None of them is really similar to a tall apartment or office building.
