I’ve always imagined crafting a stone monument that could weather centuries of weather and war. Maybe a 17th‑century observatory, built with granite blocks and lime mortar, or a 14th‑century bridge using precise arches. Which era do you think would benefit most from a structure that truly outlasts time?

I can see it now, a granite arch rising from riverbed to riverbed, each stone laid with the kind of precision that would make a 14th‑century mason proud. The mortar would have to be a slow‑setting lime, giving the whole structure time to bond under the pressure of siege engines and cannon fire. And after all those centuries of rain and winter storms, the bridge would still stand, a silent witness to trade, war, and quiet village life. The logistics—moving massive blocks by ox‑drawn carts, mixing lime in the sun—would be a research project in itself, but the payoff would be a bridge that future generations could still walk over without looking at the ground below.
