This two-room schoolhouse served the city for 101 years. Deactivated in 1961, it was sold to the Marshall Historical Society in 1968. Since that time much restoration has been done. Capitol Hill School has been re-roofed, the building tuck-pointed, its surface ground and seal coated, and the trim painted. The bell tower, inspired by a photo of the school before the turn of the century, was reproduced as closely to the original as possible.
In 1972 it was listed on the National Register of Historic Places and is also listed on the Historical American Building Survey.
Inside the school, one room has been set up as a 19th century classroom. The other room is a museum for and about children, including antique doll buggies, hobby horses, bicycles, dolls, toys and doll dishes.
