Ancillary Column

Vertical element with a small cross-section, added to the wall or pillar, used in church and secular construction in the period from the 11th to the 15th centuries. It performed the static transfer function, through the ribs, of the weight of the rib vault on the ground. Used as a structural and decorative element. The vertical ancillary column connects with the ribs of the vault, creating a unique passage between the wall and the vault.
