What is a transverse arch?

A transverse arch is defined as an arch that crosses from one side of the nave to the other at a 90-degree angle. This type of arch is integral in Gothic architecture, as it helps to support the ceiling and bear the load of the structure above. It provides lateral stability to the building and plays a crucial role in the overall architectural design by helping to transfer the weight of the ceiling and roof down to the columns and walls.

In context, choices that describe other types of arches—such as those that span across the nave or provide support to specific areas like the choir or the façade—do not fully capture the defining characteristic of a transverse arch, which is its distinctive crosswise placement relative to the nave. Understanding this allows for a deeper comprehension of how Gothic architecture utilized various arch types to create structurally sound and aesthetically pleasing spaces.
