The church is also a close copy of a medieval English church in Monken Hadley and is described as a fine example of the Gothic tradition. Both are presented as part of the Greeley heritage in Chappaqua.","narrative":"Set on a gentle rise at 191 South Greeley Avenue in Chappaqua, this fieldstone Gothic church was built in 1904-1905 on former Greeley farmland. Gabrielle Greeley Clendenin, Horace Greeley's only surviving child, and her husband, the Rev. Clendenin, built it as a memorial to their daughter Muriel. Manhattan architect Morgan M. O'Brien designed it as a close copy of a church of the same name in Monken Hadley, England, using stone from the Greeley farm. The cruciform building has an antique English window, a replica of the English font, stained glass by Wilbur Herbert Burnham and a ten-bell carillon in its crenellated tower. Beside it stands Greeley Grove, evergreens that Horace Greeley planted around 1856 as a windbreak. He held a large political reception there during his 1872 presidential campaign. Both church and grove are valued for their link to the Greeley family and for the church's architecture. It remains an active Episcopal congregation.","period_of_significance":null,"architect_builder":"Architect: Morgan M.
