The Oregon Convention Center is a convention center in Portland, Oregon. Completed in 1989 and opened in 1990, it is located on the east side of the Willamette River in the Lloyd District neighborhood.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 1, 2026. The linked authority identifier is Q7101153. Authority coordinates are 45.529, -122.663. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
