Donora, Pennsylvania
borough in Washington County, Pennsylvania, United States
Donora is a borough in Washington County, Pennsylvania, United States, approximately 20 miles (32 km) south of Pittsburgh along the Monongahela River. The population was 4,558 as of the 2020 census.
Donora was incorporated in 1901. It takes its name from a portmanteau of tin plate and steel magnate William Donner and Nora Mellon (1878–1973), wife of banker Andrew W. Mellon. The borough's nickname is "The Home of Champions", mainly because of the large number of famous athletes who have called Donora their home, including Baseball Hall of Fame outfielders Stan Musial and Ken Griffey Jr.
During the 1948 Donora smog, air pollution killed 20 people and caused respiratory problems for 6,000 of the 14,000 residents. Agriculture, coal-mining, steel-making, wire-making, and other industries were important to Donora early in its history; its Rust Belt location has lost most of its industrial capacity. It is in the "Mon Valley", 5 miles (8.0 km) downriver from Charleroi and 25 miles (40 km) upstream of Braddock.
In 1911 Donora was the 3rd wealthiest borough in the United States.
History
In 1794, the Whiskey Insurrectionists held several meetings at Fells Church, approximately 1 mile (1.6 km) east of Donora.

Why this record matters
The phrase “borough in Washington County, Pennsylvania, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 20, 2026. The linked authority identifier is Q1134745. VIAF identifies the subject as 126712904. The Library of Congress control number is n83232581. Authority coordinates are 40.176, -79.861. 5 of 6 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020, 1901, 1878 and 1973.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. 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.
