Its brick Greek Revival farmhouse is described as one of the finest in Erie County. The Olmsted Camp is presented as an outstanding turn-of-the-century family summer retreat, with Arts and Crafts buildings and naturalistic grounds designed by Harold Olmsted.","narrative":"This 188.40-acre property in Sardinia, Erie County, combines a working farm with a family summer camp. Horace Rider assembled the land from the Holland Land Company in 1827 and 1828, and his son-in-law James Hopkins is believed to have built the brick farmhouse in the 1840s. The house is Greek Revival, with wooden trim adapted from Asher Benjamin's builder's manuals, and it stands among timber-framed farm outbuildings dating from the 1870s to the 1930s. In the southwest corner, the Olmsted Camp began in 1898 when a Buffalo family started leasing land there. Its five wooden Arts and Crafts buildings include a main cabin, a dormitory and three small cottages. They sit within a naturalistic lawn and flower garden laid out by Harold Olmsted, who designed the camp. The property is significant for architecture, agriculture and recreation, with a period of significance from about 1840 to 1926. The fields are still farmed and the camp is still used each summer.","period_of_significance":"ca. 1840-1926","architect_builder":"Dwelling: unknown; camp: Harold L.
