The oldest commercial building in Wauwatosa, the Little Red Store was built in 1854 by Dr. Levi Halsted in the center of the village at the intersection of the Plank Road, the Menomonee River and the railroad. It served as the community’s first railroad depot and express office, and it remains the oldest standing post office building in Milwaukee County. The Little Red Store was designated a city landmark by the Wauwatosa Landmark Commission in 1978 and a historic structure under the city’s historic preservation ordinance in 1998. The property is designated for its historic significance.
