In page Somerville College, Oxford:

"

In 2011 student satisfaction was rated in some categories as the highest in the university.[1] Central to the college is its large quad, onto which most accommodation blocks back; it is often filled with students in summer. Somerville is one of the few Oxford colleges where students (as opposed to just fellows) may walk on the grass.[2][3] Somerville is sometimes nicknamed The Ville. Formal Halls take place on some Tuesdays and Fridays about six times a term.[4] No gowns are worn and the grace is Benedictus benedicat. The college song is 'Omnes laetae nunc sodales'.
