In the 15th century, the canons of Oseney Abbey attended lectures at Oxford University.

A site was found at the eastern end of what is now the modern frontage of Balliol College.

[3] The college was located on the east side of New Inn Hall Street and a gateway still remains.

[4] For many years the house was the official residence of the Regius Professor of Medicine at Oxford University.

The surviving buildings of the medieval college and the Norman town house that preceded it have been studied by Professor John Blair, who has reconstructed the plan of the site.
