Winchester is unusual in having its own museum, known as the Treasury, which houses the College's collection of Greek vases together with the Duberly collection of Chinese porcelain. The Greek vases were assembled in the late 19th century as a teaching aid, and the Chinese porcelain was bequeathed to the College by Major Montagu Duberly and his wife Lady Eileen Stopford in memory of their son James, a Wykehamist, who was killed during the Second World War.
There are also Egyptian, Roman and Honduran antiquities which are sometimes on display. Among the archaeological items in the Treasury is a series of pottery fragments from the bronze age site at Phylakopi on the Aegean island of Melos. The Greek vase collection has been published in the Corpus Vasorum Antiquorum: Fascicule 19, Winchester College.
