St William’s College, a Mediaeval building in York which was originally built to provide accommodation for priests attached to chantry chapels at nearby York Minster.
The college was founded in c.1465 by George Neville and the Earl of Warwick to house twenty-three priests and a provost. While the college was not a monastic establishment, it was affected by the Dissolution of the Monasteries and the college then passed into secular ownership.
The building was bought by the Province of York in 1912 for use by its convocation.
