Spirit House, also known as Timothy Brown House or Brown's Hall, is a historic home located at Georgetown in Madison County, New York. It was built about 1865 and is essentially a square, wood-frame structure. The exterior features two-by-fours arranged vertically and scalloped at regular intervals. The use of the scallop pattern gives the Spirit House a highly textured surface and it is almost impossible to discern how it is constructed without close inspection. It also features a three tiered cornice with downward pointing keys. It was constructed as a residence and for meetings of Spiritualists in a large hall on the second floor. It was listed on the National Register of Historic Places in 2006.
