Vaulting is the arched stonework forming a roof. Fan vaulting, the vaulting above, ribbed vaulting.
The ribs carry the load down to the columns, which is what let medieval builders replace walls with windows. Fan vaulting is an English speciality, and King's College Chapel in Cambridge has the largest anywhere.
