A clasping or clamped buttress has an L-shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the corner ...
Romanesque buttresses are generally of flat square profile and do not project a great deal beyond the wall. In the case of aisled churches, barrel vaults, or half-barrel vaults over the aisles helped to buttress the nave, if it was vaulted. In the cases where half-barrel vaults were used, they effectively became like flying buttresses. Often ...

These allowed the construction ...
