I'm dumb so, no particular technology comes to my mind. However, isn't all ancient technology amazing? How our forefathers invented this and that, we've reached this place because of their efforts. That just makes any piece of human-made technology amazing, maybe except Nuclear Bombs. Although, I do think it must've been a proud moment for our forefathers when they learned how to make fires.
I remember watching a you tube video about how the cement used in ancient Roman architecture has proven to be super durable. I don't remember details but it was interesting.
This is a great article, lays out the composition that makes Roman concrete last and self heal!
Oh great I will check that out!
