Built in the mid-1870s by Philip Showers, who then owned the adjacent stone Adam Stephen House, the Triple Brick Building appeared in early tax records as the "Tribble (Triple) House" or "the brick house divided into three dwellings." Because Martinsburg was an important railroad center after the Civil War and the building stood close to the railroad, its apartments were rented to railroad workers and their families. It is one of the earliest examples of apartment building housing in Martinsburg. William Evers donated the house to the city of Martinsburg in 1959, and the General Adam Stephen Memorial Association remodeled it during the 1970s, opening it as a town museum in 1981. It now contains artifacts and memorabilia of life in old Martinsburg, including items related to the town's industrial, social, and cultural history from the 1700s to the mid-1900s, as well as late-18th-century china, glassware, and pottery shards uncovered during archaeological excavations on the Adam Stephen House property.
