Metzenbaum U.S. Courthouse, also known as the Federal Building and U.S. Courthouse, is a monumental anchor to Cleveland's Civic Mall. Fronting the Mall and Public Square, it was the first building erected under Cleveland's 1903 Group Plan, which illustrates the urban planning ideals of the City Beautiful movement.New York Architect Arnold W. Brunner (1857–1925) designed this imposing building under the direction of Supervising Architect of the Treasury James Knox Taylor (1857–1929). It is one of 35 buildings constructed during Taylor's tenure (1883–1912) that were designed by independent architects commissioned by the U.S. Treasury Department under the Tarsney Act. The 1893 Act authorized the Secretary of the Treasury to use private architects, selected through competitions, to design Federal buildings. As a process, it manifested the growing demand for greater architectural standards for public buildings and opened the way for additional appropriations to maintain those standards.
