Historical research, not completeness
Castle Atlas exposes 26,802 source-identified fortified sites across 156 country/territory codes. The count describes the committed source-bounded snapshot and does not guarantee complete world coverage, complete profiles, or error-free source data.
Not live visitor or travel advice
Opening hours, access, safety, fees, transport, closures, and legal requirements can change. Verify them with current operators and authorities before acting or spending money.
Source and license boundaries
Wikidata discovery records are provided under CC0. Wikimedia media and other imported material retain their own creator, attribution, license, and source-page requirements. The project’s code license does not relicense imported content.
Product availability
The native iOS source has a locally verified release build. This website does not promise App Store availability, production accounts, live remote data, or active purchases until those systems are separately verified.
Corrections
Source-backed corrections are welcome through support. A correction request should identify the site, disputed field, preferred source, and reason. Uncertainty may be preserved rather than forced into one answer.
