# Richardsonian Romanesque (リチャードソニアン・ロマネスク)

> A late-nineteenth-century American architectural style in which H. H. Richardson recast medieval Romanesque round arches as rough masonry, deep openings, asymmetrical towers and low-spreading masses. Rather than surface decoration, stone weight, shadow depth and broad arches grouping entrances gave churches, libraries, courthouses and stations their public force.

- Kind: Style · Family: Historical Styles · Era: 1870s–1890s
- Mood: Trust, Luxury, Calm
- What this family collects: Named for the eras that produced them, these are largely architectural and interior vocabularies, and most were dug up by later centuries and given a second life.

## Brief inputs

Supply these before production. They are intentionally not invented by the style.

- Deliverable and channel: page, app screen, deck, campaign image, garment, object or space
- Subject and message: what the audience must notice or understand first
- Audience and context: where, when and at what viewing distance it will be encountered
- Format: dimensions, aspect ratio, responsive states, slide count or physical constraints
- Content hierarchy: required copy, data, actions, imagery and legal information
- Production constraints: accessibility, materials, budget, image rights and delivery deadline

## Defining characteristics

- Broad, deeply recessed round arches grouping entrances and windows
- Thick rough-faced masonry crossed by bands of contrasting stone
- Asymmetrical towers with conical roofs above a low horizontal silhouette
- Openings stepping back into the wall, with carving confined to capitals and voussoirs

## Best used for

- Giving libraries, schools or civic buildings trust through material weight instead of applied ornament
- Gathering a hotel or shop entrance into one large arch to create depth and shelter

## Composition recipe

- Typography & lettering: Fit a broad serif title into a voussoir band and do not add ornamental lines finer than the stone joints.
- Layout & structure: Group round arches of different sizes into a low horizontal body, add one tower to one side, and pull openings deep enough to reveal wall thickness.
- Material & texture: Lay large blocks of rough sandstone or granite, changing color or finish only at arch stones and horizontal bands, with dark timber and metal set farther back.

## Colour

Read off the reference works below, so a direction rather than a fixed palette.

- Ground: #B69B78
- The colour it is remembered by: #8B6250
- Text and outlines: #252322

## Evidence and rights boundary

- Treat the source of record and reference works below as evidence for understanding the style, not as assets to reproduce.
- The AI interpretation image, when present, is a browsing aid only. It is neither a reference work nor evidence for the definition.
- For a branded design system, translate hierarchy, spacing, colour roles and component logic into an unrelated fictional service. Do not copy logos, proprietary type, icons, product copy, screenshots or exact component geometry.
- For a regional, Indigenous or community-rooted tradition, retain place, authorship and historical context. Do not combine unrelated motifs or reduce the entry to generic ethnic decoration.
- For fashion and subculture, distinguish documentary context from a costume prompt; use fictional adults and avoid real labels, public figures and caricature.
- Record the rights status and intended use of every supplied image, typeface, logo and quotation before production.

## Translate it by medium

The rules below preserve the visual grammar without copying a historical artefact literally.

### Web and app

- Page structure: translate “Group round arches of different sizes into a low horizontal body, add one tower to one side, and pull openings deep enough to reveal wall thickness.” into the hero, section rhythm and information hierarchy.
- Type system: use “Fit a broad serif title into a voussoir band and do not add ornamental lines finer than the stone joints.” for display moments and short labels. Keep body copy, navigation, forms and status text in a highly legible companion when the display treatment reduces clarity.
- Components and imagery: carry “Lay large blocks of rough sandstone or granite, changing color or finish only at arch stones and horizontal bands, with dark timber and metal set farther back.” through image treatment, borders, dividers, cards and selected surfaces; do not decorate every component equally.
- Tokens: begin with #B69B78 as the ground, #8B6250 as the memorable colour, and #252322 for text, outlines and high-contrast detail. Assign colours by semantic role before tuning individual components.
- Presentation: render the screen itself as the design artefact. Add a phone, browser chrome or perspective mockup only when the deliverable explicitly asks for one.
- Responsive behaviour: preserve hierarchy, alignment logic and the dominant cue when columns collapse; do not reproduce a desktop composition by merely shrinking it.
- Usability gate: keyboard focus, action labels, contrast, zoom and reduced-motion behaviour remain explicit even when the historical style did not account for them.

### Slides and decks

- Title slide: express one idea with the strongest scale, alignment or framing move from “Group round arches of different sizes into a low horizontal body, add one tower to one side, and pull openings deep enough to reveal wall thickness.”.
- Content slides: keep the reading layer quieter than the title layer. Use one dominant characteristic per slide and repeat the same grid, margins and type roles across the deck.
- Images and surfaces: art-direct crops, masks, rules and backgrounds with “Lay large blocks of rough sandstone or granite, changing color or finish only at arch stones and horizontal bands, with dark timber and metal set farther back.” rather than adding unrelated decoration.
- Charts and diagrams: use #B69B78 as the ground, #8B6250 as the memorable colour, and #252322 for text, outlines and high-contrast detail; preserve labels and numerical contrast before stylistic treatment.
- Presentation: deliver a flat slide canvas by default. A photographed screen, laptop or conference room is a different deliverable and must be requested explicitly.
- Sequence: alternate emphatic slides with quiet explanatory slides so the style has rhythm instead of becoming constant noise.

### Image generation and art direction

- Subject: choose one concrete subject that serves one of the uses above; the style is the treatment, not the subject.
- Composition: build the frame from “Group round arches of different sizes into a low horizontal body, add one tower to one side, and pull openings deep enough to reveal wall thickness.”. Make the focal hierarchy readable before adding texture.
- Lettering and graphic marks: follow “Fit a broad serif title into a voussoir band and do not add ornamental lines finer than the stone joints.”. If text is not essential, omit it; if it is essential, use short neutral wording and reject illegible pseudo-text.
- Surface, light and finish: interpret “Lay large blocks of rough sandstone or granite, changing color or finish only at arch stones and horizontal bands, with dark timber and metal set farther back.” as material, texture, edge quality, depth and lighting rather than as a generic filter.
- Effect discipline: gradients, bloom, glass, chrome, heavy shadows, grain and distressed paper are off by default unless the material direction names or clearly requires them.
- Cliché test: remove the most obvious period prop or motif. The style should still read through composition, type, colour relation and material behaviour.
- Set direction: make a clear establishing composition, a changed crop or viewpoint, a material/detail study, and a reduced alternate. Keep the visual grammar stable while changing the framing.

### Styling, objects and spaces

- Silhouette and proportion: translate “Group round arches of different sizes into a low horizontal body, add one tower to one side, and pull openings deep enough to reveal wall thickness.” into the distribution of volume, balance, symmetry or asymmetry.
- Materials and finish: start from “Lay large blocks of rough sandstone or granite, changing color or finish only at arch stones and horizontal bands, with dark timber and metal set farther back.”; choose real materials whose behaviour supports the style instead of printing a motif onto an unrelated surface.
- Graphic detail: apply “Fit a broad serif title into a voussoir band and do not add ornamental lines finer than the stone joints.” only where lettering, labels, trims or wayfinding have a reason to exist.
- Palette: use #B69B78 as the ground, #8B6250 as the memorable colour, and #252322 for text, outlines and high-contrast detail. Let one role dominate, one support and one provide legibility or edge definition.
- Edit: carry two or three defining characteristics strongly. Avoid turning every characteristic into a literal prop or costume reference.

## What to avoid

A round arch alone is not Richardsonian Romanesque. Distinguish it from an ancient or medieval reconstruction through its American civic program, rough massing, asymmetry and deeply recessed openings.
