The Milwaukee County Historical Society, also known as MCHS, is a local historical society in Milwaukee County, Wisconsin. Founded in 1935, the organization was formed to preserve, collect, recognize, and make available materials related to Milwaukee County history. It is located in downtown Milwaukee in the former Second Ward Savings Bank building. MCHS houses the Harry H. Anderson Research Library and a museum. The library collects and preserves manuscripts, records, photographs, and family history information. The museum preserves three-dimensional artifacts related to Milwaukee County history, including paintings, ribbons, uniforms, flags, furniture, and china in a collection of over 20,000 items. Locations In addition to the main museum and research library, the MCHS owns three historic house museums and one historic site: the Lowell Damon House in Wauwatosa; the Kilbourntown House in Estabrook Park; and the Jeremiah Curtin House and Trimborn Farm in Greendale. Benjamin Church House The Benjamin Church House (also known as Kilbourntown House), a wood and brick residence, was built during 1843–1844 by a pioneer carpenter of that name in Kilbourntown, a settlement on the west side of the Milwaukee River. In 1846, Kilbourntown merged with Juneautown on the east side of the river and Walker's Point to the south to create Milwaukee, today the largest city in Wisconsin. The house, located on Fourth Street between West Cherry and West Galena Streets, was constructed in Greek Revival style architecture with four front columns and symmetry of floor plan. This style was also known as Greek temple or national style. In the 1930s, the house was recognized as having historical value worthy of rescue, with local Cream City brick and hand-hewn timbers among its distinctive features. In 1972, the Benjamin Church House was added to the National Register of Historic Places. Trimborn Farm and the Jeremiah Curtain House Trimborn Farm is a Victorian era estate located in Greendale, Wisconsin. Spanning 7.5 acres (18.5 hectares) and nine buildings, it is listed on the National Register of Historic Places. The farm is also a State Historic Site and designated Milwaukee County Landmark. Property highlights include: Farmhouse — Constructed in Greek Revival style during the 1850s using Cream City brick, a distinctive, light colored brick made locally. Granary — Built in the 1850s using a technique on the interior called brick noggin to protect against air infiltration. This building functioned as a bunkhouse and granary. Lime kilns — In the 1840s and
