James Dwight Dana House

The James Dwight Dana House, also known as the Dana House, is a historic 19th-century Italianate house at 24 Hillhouse Avenue in New Haven, Connecticut, in the United States. This building, designed by New Haven architect Henry Austin, was the home of Yale University geology professor James Dwight Dana . It was declared a National Historic Landmark in 1965 for its association with Dana, who produced the first published works emphasizing that the study of geology was a much broader discipline than the examination of individual rocks.
The Dana House consists of three roughly rectangular painted brick sections, 2-1/2 stories in height, with a low-pitch hip roof. The main block, apparently adapted from a stock pattern by New Haven architect Henry Austin, has a three-bay front facade, with a single-story porch extending across its width, supported by turned posts. The building's roof has typical Italianate wide eaves, with a wooden soffit and corbelled brickwork arches underneath. A square cupola rises above the main block. Additions on 1896 and 1905 extended the house to the north and east, stylistically sympathetic to the main block. The interior has retained much of its original handiwork.
