An old picture of Mob Quad

Mob Quad is a four sided group of buildings in Merton College, Oxford surrounding a small lawn. It was probably begun soon after the foundation of the College in 1264 and as it was completed before the middle of the next century it has a strong claim to be the oldest quadrangle in Oxford. The model has been copied, or perhaps independently discovered, at many other colleges and universities world wide.

The north and east ranges, of three and two storeys respectively, are still used as undergraduate accommodation. In the north east corner, there is a building of special interest. The roof in this corner is much steeper than the rest of the quad; this is because it is made entirely of stone. It covers the college's Muniments Room and is made of stone to protect the room from fire. This room, with its archway beneath, stands on the site of the original house purchased by Walter de Merton from a merchant of Oxford called Jacob the Jew in 1264. The receipt is still kept in the Muniments Room. Walter de Merton (c. ...
