The ribbed vault was used by Gothic architects to give the buildings flexibility in roof and wall engineering. These vaults were easier to construct when comparing them to the barrel vault, and they were also stronger and more flexible. Moreover, the vault was lighter, easier to build, economical and more enduring.
Ribbed vaults are made by connecting arches; it incorporates two diagonal arches reaching from corner to corner, along with other arches that span the length and side of the vaults. The placement and spaces between the ribs are engineered in such a way that the pressure from the ceiling is transferred to the piers. This revolutionized the interior of buildings as it opened up interior spaces.
