Confederate Monument

The Confederate Monument of Morganfield, Kentucky is a monument to Confederate soldiers from surrounding Union County, Kentucky. It is in the northernmost corner of the city cemetery, Odd Fellows Cemetery,  just outside of downtown Morganfield. During the War, "Union" County was mostly a Confederate-sympathizing county. The county produced 657 soldiers for the Confederacy, but only 187 for the Union, although 131 African-Americans joined the Union forces in 1864. In July 1862, Union forces at Caseyville, Kentucky threatened to arrest everyone in the town of treason, eventually freeing all but nineteen citizens. A skirmish in Morganfield on September 1, 1862 resulted in a Confederate victory.

The monument consists of a limestone base supporting a white marble obelisk. Inscribed on the monument are the names of sixty-four soldiers who had died in battle. Due to its age, much of its text is now illegible.

On July 17, 1997, the Confederate Monument of Morganfield was one of sixty-one different monuments related to the Civil War in Kentucky placed on the National Register of Historic Places, as part of the Civil War Monuments of Kentucky Multiple Property Submission.

Morganfield Commercial District

The Morganfield Commercial District is a 6-acre historic district in Morganfield, Kentucky which was listed on the National Register of Historic Places in 1984.

It includes parts of Main, Court, and Morgan Streets and 30 contributing buildings. It is a cohesive group of late 19th and early 20th Century commercial structures. Although most are vernacular in style, together the buildings form a tightly knit collection, which is impressive in its variety. The historic commercial area came to maturity during the period between 1870 and 1930, a time of significant growth and development in Union County. This collection of buildings is representative of that important point in time.

Included in the district are:

• Union County Courthouse, which is separately listed on the National Register.
• J.K. Waller Building, an elaborately detailed two and one-half story building with terra cotta trim and a metal cornice
• Old National Bank of Union County building

It is located on Kentucky Route 1180 east of its junction with Proctor Road. It is a two and one-half story, double-pile Greek Revival house of brick common bond construction upon a stone foundation. It was listed on the National Register of Historic Places in 1990.

 Union County Courthouse

The Union County Courthouse in Morganfield, Kentucky was placed on the National Register of Historic Places on November 17, 1978. The current courthouse is the third one for Union County and was opened in 1872. The Public Works Administration would later double the size on the courthouse.

Union County was named due to the near unanimous decision of the county's citizens to split from the county it was previously in, Henderson.

The first county courthouse for Union County was built in 1811-1812. The second courthouse was built in 1819-1820 and would later be destroyed during the Civil War. The current courthouse was built in 1871-1872.

Although born in Kentucky, Abraham Lincoln gave only one political speech in that state. This speech was presented at the Union County Courthouse. It was in 1840 when Lincoln, at the age of 31 and an elector from Illinois, campaigned for the Whig presidential candidate William Henry Harrison. This was done after Lincoln led a parade from Shawneetown, Illinois with white horses pulling floats carrying ladies.
