Meh, we also know now Romans used to mix lumps of calcium into their concrete to make cracks self repair, the "moisture" is by far not the issue. There are plenty of examples across Europe of 400 AD architecture still in good condition, the destroyed ones are usually either explicitly bombed to fuck in one of the hundreds of wars, or just uncared for and destroyed by accelerated erosion as modern infrastructure is built around them. And the occasional earthquake too, when talking about Italy and Greece.

Reply to comment by Gullible-Annual-6085 in eli5 why ancient historical buildings haven’t been kept up? Why are buildings like the Parthenon and the Colosseum in such disrepair? Greece and Rome/Italy have existed the entire time? by PickledSpace56
