One of the most dramatic parts of the museum is the Cast Courts in the sculpture wing, comprising two large, skylighted rooms two storeys high housing hundreds of plaster casts of sculptures, friezes and tombs. One of these is dominated by a full-scale replica of Trajan's Column, cut in half in order to fit under the ceiling. The other includes reproductions of various works of Italian Renaissance sculpture and architecture, including a full-size replica of Michelangelo's David. Replicas of two earlier Davids by Donatello's David and Verrocchio's David, are also included, although for conservation reasons the Verrocchio replica is displayed in a glass case.
Which Ancient Roman monument is replicated in full-scale in the Cast Courts?
