The DeCordova Museum gathers a startling amalgamation of architectural styles into one complex exhibition space. The original building, constructed in the 1880s as the summer home of Julian de Cordova, combines an eccentric mix of Moorish, Norman, Gothic, and Romanesque elements, remodeled with Bauhaus additions by John Quincy Adams. Kallmann, McKinnell and Wood's recent fifteen-thousand-square-foot brick and glass addition quadruples the museum's gallery and collection space. The wing creates a dialogue between the interior and exterior of the museum through its extensive use of glass and multilevel terraces, uniting the museum building with the thirty-five-acre Sculpture Park and two hundred surrounding acres of conservation land.
