Built about 1840, the John Curran House is the oldest surviving structure in Madison, predating the arrival of the railroad and the founding of the town in 1856. John Curran, an Irish immigrant and wagon maker, owned the property from 1839 to 1851. The house is an excellent example of Greek Revival architecture as applied to a modest residential structure. Listed in the National Register of Historic Places, it is also known as the Hoy House after longtime residents Tom and Maymie Hoy.
