It is the location of, or nearest community to, at least two historic sites that are or once were listed on the National Register of Historic Places: the Thompson Store and Maplewood Farm.^[2]

The community itself was described as a crossroads community in a 1988 study of historic resources in the county. However, it was deemed not being worthy of listing on the National Register as a historic district, because too many of its older structures had been demolished and replaced.^{[3] : 9}
