Round Arches and Heavy Stone: How to Recognize American Romanesque Revival Architecture

American Romanesque Revival architecture is identified by its thick stone walls, deep-set windows, and prominent rounded arches, often featuring robust towers and asymmetrical facades. This style, heavily influenced by H.H. Richardson, emphasizes massiveness and permanence, making it distinct from Gothic Revival's verticality.

Spot a building with thick stone walls, deep-set windows under rounded arches, and a tower or two rising over an asymmetrical facade, and you are almost certainly looking at American Romanesque Revival. The style arrived from Europe in the mid-19th century, drew its forms from the 11th- and 12th-century Romanesque architecture of medieval Europe, and reached its full, dramatic flowering in the 1870s and 1880s under the architect Henry Hobson Richardson. I find it one of the most satisfying styles to identify in the wild, because its signals are big, bold, and hard to miss—once you know what to look for.

Understanding American Romanesque Revival Architecture

Here is the part that trips people up first: what Americans call Romanesque Revival is actually a second revival. The medieval Romanesque style of the 11th and 12th centuries was itself a revival of earlier classical Roman forms, as the Architectural Styles of America and Europe guide notes. So when American builders reached back to it in the 1800s, they were reviving a revival.

The style came ashore in two phases. The first American interpretation appeared in the mid-19th century, when architectural ideas based on the buildings of ancient Rome were imported from Europe; James Renwick Jr.'s Smithsonian Institution building in Washington, D.C., completed in 1855, is the early touchstone. Only a few public buildings went up in this mode until Richardson embraced the style in the 1870s and 1880s, according to the Pennsylvania Historical and Museum Commission's architectural field guide. The second phase—the one most people mean when they say "Romanesque Revival"—ran roughly from the 1870s to 1900.

What unites both phases is an appetite for mass. These buildings want to look permanent: thick masonry walls of stone or brick, cavernous entryways, and that dominant classical Roman arch repeated over windows and doors. The Washington State Department of Archaeology and Historic Preservation adds telling details for the later examples—corbel tables or miniature arches below the eaves, prominent belt courses that emphasize the building's horizontal lines, and arched window groups separated by small columns called colonettes.

American Romanesque Revival Identification Checklist

When I stand in front of a suspiciously castle-like building, I work through the features below systematically. No single trait is decisive on its own—towers, for instance, appear frequently but not universally—but the more boxes a building checks, the stronger the case. Round arches and heavy masonry are the anchors; everything else corroborates.

Diagnostic checklist: checking a building against Romanesque Revival's defining features
Feature	What to look for
Arches	Rounded arches over windows and entryways, with heavy emphasis around the arches; arches are the style's dominant feature
Masonry	Thick, heavy stone or brick construction; exteriors of brick, stucco, or stone; rough-cut stonework in Richardsonian examples
Openings	Thick, cavernous entryways and window openings, deeply recessed
Towers	Rounded or sometimes square towers, often capped with conical roofs
Facade	Typically asymmetrical; variable stone and brick; elaborate examples may use polychromatic, contrasting materials
Columns	Squat columns and colonettes separating groups of arched windows
Ornament	Decorative plaques with intricate or interlacing patterns; geometric medieval ornament on capitals and compound arches
Horizontal details	Corbel tables or miniature arches below the eaves; prominent belt courses; shallow-pitched roofs, sometimes in red clay tile

A building that shows several of these together—especially the rounded arches plus massive construction—can be provisionally identified as Romanesque Revival on the spot. If the arches are wide and bold and the stone rough, you can go one step further and call it Richardsonian.
