A new gymnasium (Art "Buz" Sievers Center) was completed in 2020 at the site of the 1894 structure. A new auditorium and various new classrooms were also completed for the start of the 2020-2021 school year.

Why this record matters
The subject matters to the history & society register because the source frames it as high school in Monticello, Illinois. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Feb 22, 2026. The linked authority identifier is Q6905958. Authority coordinates are 40.019, -88.572. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1894, 2019, 2020 and 2021.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. 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.
