Definition & Meaning of "squinch"

What is a "squinch"?

A squinch is an architectural element used to transition between a square base and a dome or circular structure above it. It consists of a series of corbel-like arches or brackets that curve inward at the corners, allowing the dome to sit securely on the square walls. Squinches help distribute the weight of the dome evenly and create a visually pleasing connection between different shapes. This feature is commonly found in religious buildings, such as churches and mosques, where domes are often prominent, contributing to both the structural integrity and the aesthetic design of the space.
