Hanna Jr. estate on Little Mountain Road in Kirtland Hills, Lake County, Ohio, begun in 1924 as a re-created medieval English farmstead. It includes a main house, gatehouse, caretaker's cottage, pool house, stables, covered bridge and outbuildings.","why_significant":"The estate is argued to be a convincing late medieval farmstead created for a major Cleveland philanthropist by Robert O. Derrick, a leading eclectic architect. It reflects the 1920s passion for re-creating historic settings and was a showplace of the wealthy between the wars. Its main house is an authentic English house, said to be the only one of its kind in Ohio.","narrative":"Along Little Mountain Road in Kirtland Hills, a cluster of half-timbered and stucco buildings recalls a medieval English farmstead. Leonard C. Hanna Jr., nephew of Cleveland industrialist Marcus A. Hanna, began the estate in 1924 on a 300-acre farm and architect Robert O. Derrick designed it. The gatehouse, caretaker's cottage and pool house were built by 1926, and the stables followed in 1931. The centerpiece is a house said to date from 1472, brought from Ashford, Kent, in the 1920s, reassembled in Geauga County, then purchased by Hanna and re-erected on the estate in 1947-1949 with masonry wings. The nominated portion covers about 47 acres, with other parts of the estate since subdivided. It is notable as a showplace of the wealthy between the wars and an example of the 1920s enthusiasm for re-creating historic settings. The authentic English house is described as the only one of its kind in Ohio.","period_of_significance":"1924-1949","architect_builder":"Robert O. Derrick (Robert O.
