The Alexander Thoirs House is the oldest surviving brick house in Wabasha, Minnesota, United States, and the earliest example of the brick merchant houses that characterized the city's 19th-century streetscape. It was built in two phases in 1868 and 1870 for a successful local shoemaker. The house was listed on the National Register of Historic Places in 1989 for having local significance in the theme of architecture. It was nominated for its status in the city's early housing stock, its fine Greek Revival architecture, and its embodiment of the success of Wabasha's early merchant class, which helped establish the city's own commercial importance. Description The Alexander Thoirs House is a wood frame building with a brick veneer. The main section is a two-story rectangle, with a one-and-a-half-story wing centered on one side, giving the house a "T"-shaped footprint. The foundation is cement-plastered limestone. A porch spans the front of the main wing and wraps around to attach to the side wing. The house sits prominently on a corner lot facing northeast. The house is unornamented aside from the distinctive gable returns of Greek Revival architecture. Other elements of the style include the low gables, sidehall plan, and general proportions. The brick veneer and arched windows, however, are quite atypical of Greek Revival. History Alexander Thoirs was a Scottish immigrant who had this home built for himself in 1868 shortly after arriving in Wabasha. Two years later he had additional work done on the house, which was likely when the T-wing was added. He established himself as a shoe- and bootmaker, one of the merchants who helped position Wabasha as a commercial center for finished goods in the region even before the arrival of railroad access. The unusual use of brick veneer—and the lower quality of the brick, which is fairly soft—suggest the underdeveloped construction and manufacturing industries of the time, and the lack of transportation infrastructure to deliver more refined materials and methods. The front porch was added in the 1920s. At an unknown date, an enclosed wooded porch replaced an open porch in the south corner and a canopy was added to the rear of the house to serve as a basic carport. The Thoirs House is the oldest of some 20 brick residences surviving from the 19th century in Wabasha. All were built by the first two generations of the city's merchant class, forming a distinctive architectural stock
