Since 1982, it has been located in a purpose-built gallery on the first floor of the Faculty of Classics on the Sidgwick Site of the university.

The museum is one of the few surviving collections of plaster casts of ancient Greek and Roman sculpture in the world.

Noteworthy casts include those of the Laocoön and His Sons, the Farnese Hercules, the Barberini Faun and Charioteer of Delphi.

It is a plaster cast of an ancient Greek statue of a young woman painted brightly as the original would have been, which was set up on the Acropolis of Athens, around 530 BCE.

The replica is displayed next to a second, unpainted cast as a challenge to the erroneous equation of ancient Greek sculpture with pure white marble.
