This list presents the full set of buildings, structures, objects, sites, or districts designated on the
National Register of Historic Places in
Union County, Oregon, and offers brief descriptive information about each of them. The National Register recognizes places of national, state, or local historic significance across the
United States.[1] Out of over 90,000 National Register sites nationwide,[2]Oregon is home to over 2,000,[3] and 20 of those are found in Union County.
This fine
French Second Empire house represents a style unusual in
Eastern Oregon. It was built ca. 1900[a] for Abel Eaton, a prosperous businessman, civic leader, and
mayor. It stands in the north Union
neighborhood that was the town's upscale residential area during its period of rapid growth in the late 19th and early 20th centuries.[7][8]
The buildings of Union's
downtown core and oldest
residential neighborhoods recall the town's long and vitalizing, but ultimately unsuccessful, rivalry in the late 19th century with nearby
La Grande to lead Union County in transportation, commerce, population, and
government. Significant structures include many from Union's period of rapid growth from its early years through
World War I (1870–1919), and a smaller number from the decades just after the town reached its zenith (1920–1940).[8]
