Europe

This atlas records 3,492 prisons, jails and detention centres in 51 countries of Europe. Counts depend on what each country's official registers and open map data list, so small facilities may be missing.

Russia has the most entries, with 760 prisons and jails and 6,400 police units.

Countries are grouped by sub-region (Western Europe, Central Europe, Northern Europe and Southern Europe). Each country page then lists its regions, and each region its districts and facilities.

Facilities come from official government registers where they are published, and otherwise from OpenStreetMap and Wikidata, with missing contact details completed from Overture Maps. Every source is credited on the data sources page.

Prison services in Europe rarely publish inmate lists. Contact the facility or the national prison administration using the details on each facility page.
