The Bronx County Courthouse, also known as the Mario Merola Building, is an historic courthouse building located in the Concourse and Melrose neighborhoods of the Bronx in New York City. It was designed in 1931 and built between 1931 and 1934. It is a nine-story limestone building on a rusticated granite base in the Art Deco style. It has four identical sides, an interior court, and a frieze designed by noted sculptor Charles Keck. The sculptures on the 161st Street side are by noted sculptor George Holburn Snowden. Two sculptural groups on the Walton Avenue side are by noted sculptor Joseph Kiselewski. Kiselewski collaborated with Adolph A. Weinman to create the work. The Bronx Museum of the Arts was once located on the main floor. The building stands two blocks east-southeast of Yankee Stadium, and across 161st Street from Joyce Kilmer Park.
