Richardsonian Romanesque architecture

Richardsonian Romanesque is a style of Romanesque Revival architecture named after architect Henry Hobson Richardson (1838–1886), whose masterpiece is Trinity Church, Boston (1872–1877), designated a National Historic Landmark. Richardson first used elements of the style in his Buffalo State Asylum for the Insane in Buffalo, New York, designed in 1870.

This very free revival style incorporates 11th and 12th century southern French, Spanish and Italian Romanesque characteristics. It emphasizes clear, strong picturesque massing, round-headed "Romanesque" arches, often springing from clusters of short squat columns, recessed entrances, richly varied rustication, blank stretches of walling contrasting with bands of windows, and cylindrical towers with conical caps embedded in the walling.

The style includes work by the generation of architects practicing in the 1880s before the influence of the Beaux-Arts styles. It is epitomised by the American Museum of Natural History's original 77th Street building by J. Cleaveland Cady of Cady, Berg and See in New York City. It was seen in smaller communities in this time period such as in St. Thomas, Ontario's city hall and Menomonie, Wisconsin's Mabel Tainter Memorial Building, 1890.
