The house dates to 1819 and the barn to 1840, with a contributing summer kitchen and 1916 equipment barn.","why_significant":"The house is regarded as an example of local Federal-period farmhouse architecture, with a center hall plan, brick construction and restrained interior details. The bank barn is described as the largest surviving mid-19th century barn in Cumberland Township and as a standard example of its type. The farmstead has remained in one family's ownership since 1802 and in agricultural use.","narrative":"Built of brick in 1819 on a farm in southern Cumberland Township, the Horner House is a two-and-a-half-story vernacular Federal dwelling with a five-bay south façade laid in Flemish bond and a center hall plan. Its interior has four fireplaces with individually designed Federal mantels. Alexander Horner completed it after acquiring the land in 1802. Beside it stands a bank barn finished in 1840 by the builder I. Lightner, whose inscription survives on a door brace. The barn has a cantilevered forebay, stone granaries and bent construction, and is regarded as the largest surviving mid-19th century barn in the township. A 1916 equipment barn and an early 19th-century summer kitchen complete the farmstead. The property is valued for its architecture and for the continuous family farming that has continued on the site.","period_of_significance":"1819-1916","architect_builder":"I.
