The Spring Hill (Z Bar) Ranch is a 10,894 acre cattle ranch located two miles north of Strong City in Chase County, Kansas. The ranch is located in the Flint Hills of east-central Kansas and contains a vast expanse of tallgrass prairie. Spring Hill Ranch House (built 1881; listed on the National Register of Historic Places in 1971), is an imposing three story, eleven-room building constructed in the Second Empire style, a rare architectural style in the region, and executed in native materials.
The 6,480 square foot, 3-story barn is nearly as impressive as the house. At the time of its construction, it lacked two feet of being the largest barn in the state of Kansas.
