What about stone/brick dry laid or with mortar? A lot of roman stuff is around, but there was so much to start with it could easily be selection bias.

- Retric 5y agoSome of this is selection bias, but many structures where removed because people desires change over time rather than some issue with the structure it’s self. Large dry laid stone can easily last thousands of years as long as the foundation is solid. Consider the pyramids both in Egypt and South America plus a host of other very old structures. However, you need to avoid tension, earthquakes, and unstable ground, can’t build very tall etc. High construction costs, slow build times, and serious limitations in what structures are viable shows just why we mostly abandoned the technology. Mortar is basically indefinitely replaceable with constant maintenance and has lower upfront costs. So it’s generally a much better option.
