Union County/Union Parish monument
In 1931, a monument was established at the Union County border with Union Parish, Louisiana, through the private efforts of former Arkansas Governor George Washington Donaghey (1856–1937), who was born in Union Parish and grew up in the border area before he moved as a teenager to Conway, Arkansas. As governor, he oversaw the construction of the state capitol building in Little Rock and brought about the establishment of the state health unit and its agricultural colleges.
After his gubernatorial tenure, Donaghey, who felt a kinship to both states, commissioned a park on the land about the monument. Known for its intricate carvings and Art Deco style, the monument includes references to different modes of transportation a century apart—1831 and 1931—and mentions Huey P. Long, Jr., whose educational program Donaghey admired. The land was not registered with the state parks offices in either state, timber companies cut trees thereabouts, and the monument was forgotten. In 1975, State Representative Louise B. Johnson obtained passage of a law to refurbish the monument. Restoration efforts were finally unveiled in 2009.

Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries. Arkansas townships have limited purposes in modern times. However, the United States Census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Union County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.
