Why this record matters
The subject matters to the places & architecture register because the source frames it as building in Portland, Oregon, U.S. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 14, 2026. The linked authority identifier is Q120107971. Authority coordinates are 45.494, -122.606. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1915 and 2025.
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.
