What is a defining feature of Romanesque architecture?

A defining feature of Romanesque architecture is the use of rounded arches. This architectural style, which flourished between the 10th and 12th centuries, is characterized by its robust and monumental forms, and the rounded arch is fundamental to achieving the solid and heavy appearance of Romanesque structures. The rounded arch allows for the creation of thick walls and small windows, which contribute to the fortress-like aspect of many Romanesque buildings.

In addition to the rounded arches, Romanesque architecture often incorporates barrel vaults and groin vaults. The use of these architectural elements together with rounded arches supports the overall design ethos of strength and stability.

Pointed arches, cross-ribbed vaults, and flying buttresses are more characteristic of Gothic architecture, which developed later and marked a significant evolution in architectural techniques. These elements allowed Gothic cathedrals to become taller, more illuminated, and more intricate compared to their Romanesque predecessors.
