Henry Hobson Richardson, known as one of “the recognized trinity of American architecture,” is the father of the Richardsonian Romanesque architecture style. Richardson first developed this style during his work on the famous Richarson Olmsted Complex in Buffalo, New York, in 1870. Richardson’s style incorporated 11th and 12th century southern French, Romanesque characteristics. Richardson was presumably inspired by the architecture he saw during his studies at the Ecole des Beaux-Arts while in Paris during 1860. Romanesque architecture is characterized by its use of semi-circular arches, thick walls, large towers, and decorative arcading. The Richardson Olmsted Complex features many of the same qualities with two large towers, intricate arcades, and semi-circular windows throughout the building. It is made of large Medina red sandstone and brick. The roofing is copper-green and is sharply slanted. The building is made of a central administrative tower and five pavilion wards set back on each side, totaling eleven buildings in all. The buildings are all connected by two-story curved corridors.
