The parish halls echo its Gothic design, and the 1893 rectory represents late-nineteenth-century domestic architecture. The complex retains a high level of integrity and serves as a local landmark.","narrative":"Trinity Episcopal Church Complex occupies a block-sized lot of just under one acre in Mount Vernon, New York. Its centerpiece is a granite Gothic Revival church built in 1857-59 to designs by the English-born architect Henry Dudley, who drew on English parish church models with a steep slate roof, buttresses and lancet windows. The church was extended and redecorated in the 1880s, gaining a narthex, a rose window and a baptistry. An old parish hall (1892) and a new parish hall (1909) were attached in matching Gothic style, and the latter was rebuilt inside its original stone walls after a fire in 1954. A wood-frame rectory followed in 1893. Together the buildings illustrate the lasting appeal of the Gothic mode and the ideals of the Ecclesiological movement, which favored honest materials, stone construction and clearly separated functional spaces. The complex remains a local landmark and has served the Mount Vernon community since the parish formed in 1856.","period_of_significance":"1857-1930's","architect_builder":"Henry Dudley (architect); James C.
