The four-acre (1.6 ha) park[14] stands at the southernmost point of Roosevelt Island. Looking south, the visitor has a clear view of the headquarters of the United Nations (particularly the United Nations Secretariat Building); to the north of the park is the Queensboro Bridge, which spans the East River.[2] Approaching from the north, the visitor passes between a double row of trees that narrow as they approach the point, framing views of the New York skyline and the harbor.[3] The memorial is a procession of elegant open-air spaces, culminating in a 3,600-square-foot (330 m2) plaza surrounded by 28 blocks of North Carolina granite, each weighing 36 tons.[2] The courtyard contains a bust of Roosevelt, sculpted in 1933 by Jo Davidson.[4]
