Granite Mansion was a historic home located at Newark in New Castle County, Delaware. It was built in 1844, and was a three-story, three-bay, cubic stuccoed stone building with a flat roof in the Greek Revival style. It had a rear kitchen wing. The house was renovated in 1924 in the Neoclassical style, to add a two-tiered Corinthian porch on the east elevation and a Doric Porte-Cochere on the west elevation. Also on the property were a small stuccoed spring house and one-and-a-half-story frame and stucco building dated to 1924.[2] The house has been demolished and the property occupied by the First Presbyterian Church of Newark.
