Bridges of memory

About the project

“Česko × Ukrajina” is an open trilingual atlas of the ties between two nations: people, events, places, organisations, projects and works from the Middle Ages to today.

How it works

Every subject has its own dossier: essence, timeline, connections and numbered sources. Dossiers are plain text files in one folder; the site reads them directly, so every correction is visible at once and has a change history.

Two banks

The “River of time” shows two currents: Ukrainians in Czechia and Czechs in Ukraine. Where a dossier is still missing, we say so openly and direct further research there.

Always with a source

The atlas tells stories of cooperation, culture, science, education and mutual support. Every news item has a primary source and a date. Uncertain points are marked as disputed; a hypothesis is never presented as fact.

An AI desk with a human at the end

Dossier texts, news scouting, translation and pre-sorting of feedback are done by AI — Claude models by Anthropic, matched to the difficulty of each task. Every quote is mechanically matched against the source page, and facts are checked by a different, independent model. New dossiers appear as “Draft”, and only a person can set the level “Confirmed by an editor”. All steps are described on the “How we verify” page.

Open data

All public dossiers are available as JSON: /api/open/dossiers.json. Atlas texts are CC BY 4.0; rights to sources belong to their owners.

  • Confirmed by an editorAn editor confirmed the dossier; the reason is shown on the page. This is not an independent scholarly review.
  • Disputed pointsSources disagree; disputed points are marked in the text.
