The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q12556970. VIAF identifies the subject as 315128709. Authority coordinates are 56.151, 37.199. 2 of 3 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
