Black Assize of Oxford 1577

On the wall inside the Main Hall of the Old County Hall of Oxfordshire in New Road, an inscription reads: Near this spot stood the ancient Shire Hall, unhappily famous in history as the scene in July 1577 of the Black Assize, when a malignant disease known as Gaol Fever caused the death within forty days of the Lord Chief Baron of the Exchequer, Sir Robert Bell, the Lord High Sheriff (Sir Robert D'Oyly of Merton) and about three hundred more.
