Q » How does a pendentive support a dome over a square room?
08 Dec, 2025
A » A pendentive is a curved triangular architectural element that transitions the space between a square room and a circular dome. It supports the dome by distributing its weight down to the building's four corners. Each pendentive is formed by the intersection of a dome with its supporting arches, creating a stable base that evenly channels gravitational forces, thus allowing the dome to rest securely over the square room below.
