Richardsonian Romanesque is a style of Romanesque Revival architecture named after the American architect Henry Hobson Richardson (1838–1886). The revival style incorporates 11th- and 12th-century southern French, Spanish, and Italian Romanesque characteristics. Richardson first used elements of the style in his Richardson Olmsted Complex in Buffalo, New York, designed in 1870, and Trinity Church in Boston is his most well-known example of this medieval revival style. Multiple architects followed in this style in the late 19th century; Richardsonian Romanesque later influenced modern styles of architecture as well.
