Which mechanism limited the maximum height of the central nave in Romanesque churches prior to Gothic architecture?

💡 Explanation

When Romanesque churches increased nave height, lateral thrust from the heavy barrel vaulting pushed outwards on the walls, threatening collapse due to limited buttressing. Therefore lateral thrust was limiting, rather than timber shortage, pointed arches, or stained glass, which relate to Gothic or other architectural constraints.
