Source priority
Official operators, public bodies, municipalities and destination organizations are preferred for hours, access, rules and pricing. Editorial sources can add context, but do not replace primary facts.
Field-level provenance
A page-level source list is not enough for volatile data. Important fields can point to their own source and verification record.
Report an issue
If you find an inaccurate, outdated or unclear statement, email the operator with the page URL, the passage concerned and, where available, a supporting primary source. Correction reports are reviewed against the source and editorial record.
