ⓘWhat do the D1–D5 confidence tiers mean?›
- D1A single attributed public source (museum, council, Historic England, CWGC, mapping data).
- D2Two or more independent public sources corroborate the same facts.
- D3A named coordinator or local reviewer has confirmed the public-source account.
- D4A named observer has personally visited and documented the site — photographs, inscriptions, condition.
- D5An archive or institution has provided written documentation supporting the entry.
A higher tier means more corroborating evidence, not automatic historical certainty. The Discovery layer does not replace archival verification.
In Royal Square at Woodhall Spa, on the site of a hotel destroyed by bombing in 1943, a memorial in the form of a breached dam honours the 204 men of No. 617 Squadron RAF — the Dam Busters — who died in the Second World War. Their names are inscribed on slate set into the spillways of the dam.
