* Masonry - large, multi-storeyed buildings in stone; with high ceilings, vaulted cellars, round turrets (as opposed to the earlier square ones)
* Masonry - Large temples - probably with gothic arches and flying buttresses to allow for large windows
* Thick, diamond-shaped window panes{{ref|asos|11}}

* Mining and tunnelling - deploying an extensive tunnel and drain system deep underground, which has remained stable and safe for centuries - a large part of which is lined
