Union is situated in the Piedmont Region of South Carolina, convenient to the major metropolitan areas of Greenville, Columbia and Charlotte. Union County was named for the old Union Church near the present day town of Union. The area was settled in the mid 1700s when Scotch-Irish settlers immigrated to South Carolina from Virginia and Pennsylvania.
The town includes historic sites and architecture such as the Union County Courthouse, a neoclassical Greek building; the old Union jail, designed by Roberts Mills and built in 1823; the Culp House, a Greek revival style structure; and the Gothic-style Episcopal Church of the Nativity. Just minutes from downtown Union, Rose Hill Plantation State Historic Site offers a look at antebellum South Carolina in a serene, rural setting. It’s also the historic home of South Carolina’s "Secession Governor," William H. Gist.
