Purpose before appearance
We identify a building by original purpose, date, setting and evidence—not merely towers, battlements or a popular name.
Local terminology
Terms such as château, Schloss, Burg, alcázar, citadel and fort are explained in context rather than forced into one English category.
Evidence and uncertainty
Documented concealed spaces are separated from unverified tunnel and escape legends. Restored and reconstructed fabric is identified when reliable sources make the distinction.
Current information
Opening hours, official occupancy, political use and access rules can change. Readers are directed to the responsible government or heritage organization.

Factual corrections supported by authoritative sources may be submitted through the publisher help desk linked on the Contact page.
