Pendentives

Definition

Pendentives are architectural elements that enable the placement of a circular dome over a square room by transitioning the weight of the dome down to the corners. This innovative structural solution allows for a seamless visual transition from a square base to a dome, creating an impressive open space above. In Early Christian architecture, pendentives represented a significant advancement, allowing for grander and more ambitious church designs that facilitated the expression of spirituality and grandeur.
