History and Lower Cross Roads
Because it links Bel Air and Aberdeen (and indirectly, the only other incorporated town in Harford County, Havre de Grace), Churchville was once known in colonial times as Lower Cross Roads. The town has agricultural origins and is known for its many picturesque churches, particularly Churchville Presbyterian Church, at the center of town and Holy Trinity Episcopal Church.
Churchville was once home to the Archers, a prominent family in Maryland and United States History. Their home, Medical Hall, still stands in Churchville, and several of the Archer family are buried in the cemetery at Churchville Presbyterian Church.
Churchville is home to the champion Little-leaf Linden of Maryland, which made its debut on the list of American Forests Champion Trees in 2018. It is the largest known tree of its species in the country.
Best Endeavor, Church of the Holy Trinity, Churchville Presbyterian Church, Finney Houses Historic District, Medical Hall Historic District, and Webster's Forest are listed on the National Register of Historic Places.
