perspectivescientific

From an engineering perspective, long build times created a unique problem: technology changed while the building was going up. A church started with simple wooden pulleys might end with steam engines. The stones at the bottom had to support weight they were never designed for, forcing later builders to invent new ways to keep the walls from collapsing.
